The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

This paper tries to establish what the nuclear modification factor R_AA of high-momentum hadrons in oxygen–oxygen collisions would be if no quark–gluon plasma formed. It computes the no-quenching baseline from next-to-leading-order perturbative QCD, using three modern nuclear parton distribution sets and three fragmentation function sets. The headline result is that in minimum-bias 16O+16O collisions at 5.36 TeV, the baseline for charged hadrons is under control at roughly 5% uncertainty for transverse momenta between 20 and 70 GeV, with oxygen nuclear PDFs the main source of uncertainty. If LHC data deviate beyond that band, final-state energy loss would be demonstrated; below 20 GeV and above 70 GeV, the baseline is too uncertain for such a clean statement. The same baseline is essentially unchanged for neutral pions, and a neon–neon over oxygen–oxygen ratio cancels nPDF uncertainties to about 1%.

Core claim

The central claim is a parameter-free pQCD prediction: in minimum-bias 16O+16O collisions at sqrt(s_NN)=5.36 TeV, the charged-hadron nuclear modification factor R_AA^h is computable from QCD factorization alone, with no final-state interactions, and its theoretical uncertainty is ~5% in the 20–70 GeV transverse-momentum range. The prediction uses NLO hard matrix elements convoluted with three nuclear PDF sets (EPPS21, nNNPDF3.0, TUJU21) and three fragmentation-function sets (BKK, NNFF1.1h, NPC23), with 15-point scale variation and 68% confidence intervals. The three nPDFs agree in that window, and the FFs agree to within 5%. Above 70 GeV, NNFF1.1h deviates downward because its down-quark FF

What carries the argument

The carrying object is the QCD factorization expression for the single-inclusive hadron cross section, dσ = f_i^A ⊗ f_j^B ⊗ σ^hat_{ij→l} ⊗ D_l^h, evaluated at NLO with renormalization, factorization, and fragmentation scales set to p_T^h. The baseline R_AA is the ratio of that cross section in oxygen–oxygen to A^2 times the proton–proton cross section. Uncertainty control comes from the ratio: scale and fragmentation uncertainties cancel in numerator and denominator, and nPDF error members are matched between the oxygen and proton calculations. A diagnostic appendix shows that the high-p_T spread among fragmentation-function sets is governed by the third moment of the down- versus up-quark f

Load-bearing premise

The prediction leans on oxygen nuclear parton distribution functions that no oxygen data constrain: they come from interpolating global fits in nuclear mass number A. If that interpolation misses the gluon or sea-quark content of 16O, the 20–70 GeV baseline shifts and the quoted 5% no longer covers the truth.

What would settle it

Measure oxygen nPDFs directly with the 2025 proton–oxygen run at 9.62 TeV—e.g., via dijet or electroweak-boson production—and re-derive the oxygen PDFs without A-interpolation; if the recomputed 20–70 GeV R_AA baseline moves by more than ~5%, the central precision claim fails. Independently, high-precision minimum-bias OO data at 5.36 TeV that depart from the baseline by more than the combined experimental and theoretical uncertainty would establish the final-state signal the paper prepares for.

If this is right

  • A measured minimum-bias OO charged-hadron R_AA that leaves the ~5% band between 20 and 70 GeV is evidence of final-state energy loss; in the same window a null result would place a clean upper bound on jet quenching in systems with roughly ten participating nucleons.
  • Neutral-pion R_AA can be used interchangeably with charged-hadron R_AA, since their baselines agree within nPDF uncertainties.
  • The NeNe/OO cross-section ratio is predicted to be unity to about 1% across most of the p_T range, providing a largely baseline-independent way to look for system-size-dependent medium effects in the 2025 LHC light-ion run.
  • Proton–oxygen data at 9.62 TeV, once included in global nPDF fits, should shrink the dominant low-p_T uncertainty and sharpen the baseline.
  • The high-p_T discrepancy between FF sets is traced to isospin symmetry breaking in one set; enforcing D_d = D_u removes the anomaly, so future FF fits that restore isospin symmetry will stabilize the p_T > 70 GeV prediction.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • If the 20–70 GeV baseline agrees with data, that agreement would also validate A-interpolation for 16O at moderate x, indirectly testing the nuclear gluon distribution—something no single previous measurement does.
  • The isospin diagnosis suggests a concrete falsifiable cross-check in existing LHC data: the charge asymmetry of pions in OO or pO collisions should reflect whether down-quark fragmentation is truly suppressed relative to up quarks; if not, NNFF1.1h-style FFs would be disfavoured.
  • Extending the same ratio-symmetry argument to identified hadrons (kaons, protons) or to forward rapidities could give separate, correlated baselines whose cross-ratios are even better controlled than R_AA alone.
  • Because the nPDF interpolation is the weak point, a natural near-term test is to compare the 2025 OO R_AA in two p_T windows (20–70 GeV and below 20 GeV): a pattern that tracks the EPPS21 low-p_T dip rather than a smooth suppression would point to nuclear PDFs rather than quenching.

Referee Report

0 major / 3 minor

Summary. The paper presents NLO pQCD predictions for the inclusive charged-hadron and neutral-pion yield in minimum-bias proton-proton and oxygen-oxygen collisions at sqrt(s_NN)=5.36 TeV, assuming no final-state interactions. Using the INCNLO code with LHAPDF grids, the author convolves three nuclear PDF sets (EPPS21, nNNPDF3.0, TUJU21) and three fragmentation-function sets (BKK, NNFF1.1h, NPC23), with a 15-point scale variation prescription and matched PDF/FF error sets. The setup is validated against ALICE pp data at 5.02 TeV. The central result is that in the window 20 GeV < pT < 70 GeV the charged-hadron no-quenching R_AA baseline has an estimated uncertainty of about 5%, with nPDFs the dominant source; below 20 GeV the uncertainties are large, and above 70 GeV FF differences, traced to isospin assumptions in NNFF1.1h, become important. Additional results cover rapidity dependence, neutral pions, and a NeNe/OO cross-section ratio.

Significance. This is a timely and useful contribution: the LHC has just taken oxygen-oxygen data, and a transparent, reproducible no-quenching baseline is needed to interpret any observed suppression. The paper's strengths are its standard but careful NLO framework, the public code and data, the 15-point scale treatment, the correlated propagation of PDF/FF uncertainties between numerator and denominator, and the explicit comparison of several independent nPDF and FF determinations. The main limitation--that no oxygen data enter the nPDF fits, so the 16O nPDFs rest on interpolation in nuclear mass number A--is clearly acknowledged in Section II A and in the conclusions. I therefore regard this as a caveat on the absolute accuracy of the ~5% figure rather than an internal inconsistency; the authors correctly identify future pO data as the needed constraint.

minor comments (3)
  1. [Abstract / Conclusions] The statement that the baseline 'can be controlled at the ~5% level' should be qualified as being conditional on the current nPDF and FF uncertainty estimates and on the assumption that the A-interpolation for 16O nPDFs is unbiased. This is stated in Section II A, but the abstract and conclusions should carry the same caveat to avoid an unconditional reading.
  2. [Section III B, after Fig. 4] The text refers to 'NNFF1.0h' twice; the correct set name is NNFF1.1h. Please fix this typo in the paragraph discussing discrepancies between FFs.
  3. [Eq. (1)] The definition of R_AA would benefit from an explicit statement that the cross sections are differential in pT and integrated/averaged over the given rapidity window |y|<y_max, matching the notation used in Section II A.

Circularity Check

0 steps flagged

No significant circularity: the oxygen R_AA baseline is computed from external nPDFs and FFs, and no fitted quantity is renamed as a prediction.

full rationale

The central claim is the pQCD no-quenching baseline for R_AA in minimum-bias OO collisions. The derivation chain is Eq. (2): a factorized convolution of nPDFs, NLO partonic cross sections, and FFs, with R_AA defined in Eq. (1) as the ratio of the computed OO and pp cross sections. No parameter is fitted to oxygen R_AA data or to the oxygen data being predicted. The oxygen nPDFs are external global fits (EPPS21, nNNPDF3.0, TUJU21), and the paper explicitly notes in Section II A that 'no data with oxygen nucleus is included in the fits, and oxygen nPDFs are determined by interpolation in nuclear mass number A'. This is an untested interpolation assumption and a genuine systematic uncertainty for the 5% claim, but it is not circularity: the prediction does not reduce to its own input by construction. The validation against ALICE pp data (Fig. 1) is a sanity check, and the paper openly states the agreement is 'not surprising, since these FFs are fitted to LHC proton-proton data'; this does not force the OO/pp ratio because the same FFs enter both numerator and denominator and cancel to a large extent, with the residual FF sensitivity diagnosed in Appendix B by explicit isospin modifications. Self-citations such as Refs. [27] and [29] are used for context or as an independent LO cross-check of the numerical implementation, not as the load-bearing source of the central baseline prediction. No uniqueness theorem, no ansatz-smuggling citation, and no renaming of a known result are present. Thus the paper is self-contained against external benchmarks, and the circularity score is 0; the dominant scientific concern is the untested A-interpolation for 16O nPDFs, which is a correctness/uncertainty issue, not a circularity issue.

Axiom & Free-Parameter Ledger

0 free parameters · 5 axioms · 0 invented entities

The paper introduces no free parameters or invented entities; it uses existing PDFs, nPDFs, and FFs as external inputs. The central prediction relies on standard QCD factorization, on the interpolation of oxygen nPDFs from fits without oxygen data, and on the conventional use of scale variation to estimate missing higher orders.

axioms (5)
  • standard math QCD factorization for single-inclusive hadron production in minimum-bias collisions (Eq. 2)
    The entire computation rests on the Collins-Soper-Sterman factorization theorem; this is the standard framework for inclusive hadron spectra.
  • domain assumption Oxygen nPDFs can be obtained by interpolation in A from fits to heavier nuclei, with no oxygen data in the fits
    Section II A states that no oxygen data enters the nPDF fits and oxygen distributions are interpolated in A. This is load-bearing for the R_AA prediction at 20-70 GeV where nPDFs dominate the uncertainty.
  • domain assumption No final-state interactions (no quenching) in the baseline
    The baseline is defined by the assumption of no medium effects; this is the null hypothesis the paper computes, not a hidden assumption.
  • domain assumption Scale variation by a factor 2 (15-point prescription) is a valid proxy for missing higher orders
    The paper uses this conventional prescription to estimate perturbative uncertainty; it is stated in Section II A.
  • domain assumption Fragmentation functions fitted to e+e- and pp data are universal and apply to OO collisions
    The calculation uses BKK, NNFF1.1h, and NPC23 FFs from external fits; FF universality is a standard assumption, and the paper tests FF dependence but cannot validate it for oxygen.

I present predictions for inclusive charged hadron spectra in minimum-bias proton-proton and oxygen-oxygen collisions at a centre-of-mass energy of $\sqrt{s_\mathrm{NN}} = 5.36\,\text{TeV}$, assuming no final-state interactions. Using next-to-leading order perturbative QCD matrix elements, along with state-of-the-art (nuclear) parton distribution and fragmentation functions, I establish a baseline for the nuclear modification factor $R^h_\text{AA}$ in oxygen-oxygen collisions in the absence of quenching. Theoretical uncertainties in this baseline are found to be substantial for transverse momenta below $20\,\text{GeV}$. In the intermediate range $20\,\text{GeV} \lesssim p_T^h \lesssim 70\,\text{GeV}$, these uncertainties are significantly reduced to approximately 5\%. At higher momenta ($p_T^h \gtrsim 70\,\text{GeV}$), however, predictions exhibit a marked spread due to differences between fragmentation functions, reflecting varying assumptions about isospin symmetry. Finally, I show that considering neon-neon collisions in the initial state or neutral pions in the final state does not appreciably change the nuclear modification factor.
