The pith

No significant excess of events is observed in a search for a heavy resonance decaying to a top quark and a neutral scalar boson at the LHC.

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

This paper reports the first LHC search for a new heavy resonance that decays to a top quark and a neutral scalar boson in the fully hadronic final state. The analysis examines proton-proton collision data recorded by the CMS detector, totaling 138 inverse femtobarns at 13 TeV center-of-mass energy. It targets cases where both the boosted top quark and the scalar boson decaying to bottom quarks appear as single large-radius jets with substructure. No excess above background predictions is found in the data. The results exclude certain masses for a benchmark vector-like top quark and set cross-section limits for other scalar masses.

Core claim

The analysis finds that the data in the signal region matches the expected background from simulation and control regions with no statistically significant excess. For the benchmark model of single production of a vector-like top quark T' decaying to a top quark and a neutral scalar phi (with phi decaying to a bottom quark pair), and where phi is the standard model Higgs boson with T' width equal to 5 percent of its mass, T' quark masses from 0.85 to 1.3 TeV are excluded at 95 percent confidence level. The most stringent limits to date are set for T' masses above 2 TeV. For other phi masses, the product of T' production cross section and branching fraction to top plus phi is constrained to 0

What carries the argument

Reconstruction of highly boosted top quark and phi boson decays as single large-radius jets identified by their substructure in the fully hadronic final state.

If this is right

  • Vector-like top quarks with masses between 0.85 and 1.3 TeV are excluded at 95% CL when the scalar is the standard model Higgs and the width is 5% of the mass.
  • The most stringent limits to date apply for vector-like top quark masses above 2 TeV.
  • Upper limits as low as 0.1 fb are set on the product of production cross section and branching fraction for other scalar boson masses.
  • Combining the fully hadronic results with a previous semileptonic search strengthens the overall constraints on the benchmark model.

Where Pith is reading between the lines

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

  • These exclusions constrain models beyond the standard model that predict vector-like quarks coupling to Higgs-like scalars.
  • The jet substructure techniques developed here could be adapted to searches for other heavy resonances in fully hadronic channels.
  • Additional integrated luminosity from future LHC runs would extend the mass reach or tighten cross-section limits further.

Load-bearing premise

The background prediction from simulation and control regions accurately describes the data in the signal region, and the modeling of signal efficiency for boosted large-radius jets with substructure is correct.

What would settle it

A statistically significant excess of events in the signal region with jet substructure matching the expected top quark and bottom-quark pair signatures would indicate the presence of the new resonance.

A first search at the LHC for a new heavy resonance decaying to a top quark and a neutral scalar boson $\phi$ in the fully hadronic final state is presented, where the $\phi$ boson is identified by its decay into a bottom quark-antiquark pair. The search is focused on final states in which the decay products of the highly Lorentz boosted top quark and $\phi$ boson are each reconstructed as a single, large-radius jet with distinct substructure. The analysis is performed using proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$, recorded with the CMS detector at the LHC in 2016$-$2018. The single production of a vector-like top quark, $\mathrm{T}'$, is used as a benchmark model for the signal process. The results of this search are combined with those of a previous CMS search in which semileptonic decays of the top quark were used. No significant excess of data is observed with respect to the background prediction. For the case where the neutral scalar is a standard model Higgs boson and the $\mathrm{T}'$ quark width is 5% of its mass, $\mathrm{T}'$ quark masses between 0.85 and 1.3 TeV are excluded at 95% confidence level and the most stringent limits to date are set for masses above 2 TeV. For other $\phi$ boson masses, upper limits as low as 0.1 fb are set on the product of the $\mathrm{T}'$ quark production cross section and branching fraction for its decay to a top quark and a $\phi$ boson.

Referee Report

1 major / 3 minor

Summary. The manuscript reports a search for a heavy vector-like top quark T' decaying to a top quark and a neutral scalar φ (with φ → bb) in the fully hadronic final state. It uses 138 fb^{-1} of 13 TeV CMS data, reconstructing the boosted decays as large-radius jets with substructure taggers. No significant excess over background is observed. For φ as the SM Higgs with T' width 5% of its mass, T' masses 0.85–1.3 TeV are excluded at 95% CL, with the strongest limits above 2 TeV; results are combined with a prior semileptonic search, and cross-section limits are set for other φ masses.

Significance. If the background modeling is accurate as validated in sidebands, this provides the first dedicated fully hadronic search for this topology and meaningfully strengthens high-mass constraints on vector-like top quarks by leveraging the larger hadronic branching fraction. The channel combination and boosted-jet techniques are effective for extending sensitivity above 2 TeV where prior limits were weaker.

major comments (1)
  1. [Section 5] Section 5 (Background estimation): The central no-excess and high-mass limit claims depend on the QCD multijet and ttbar background prediction matching data after all boosted-jet mass, top-tagger, and bb-tagger selections in the signal region. While sideband validation is referenced, the manuscript should include explicit quantitative agreement metrics or plots for the reconstructed resonance mass tail above 2 TeV in dedicated control regions (without full signal selection) to confirm the extrapolation does not bias the limit-setting procedure.
minor comments (3)
  1. [Abstract] Abstract: The statement that the most stringent limits are set above 2 TeV should briefly note the specific prior results (e.g., from ATLAS or earlier CMS) being surpassed for context.
  2. [Figure 5] Figure 5 (limit plot): Add the expected and observed limits from the semileptonic-only analysis as a separate curve or band for direct visual comparison of the combination improvement.
  3. [Section 4.1] Section 4.1 (Event selection): Specify the exact jet radius parameter (e.g., R=0.8) and the numerical working points for the top and bb substructure taggers used in the final selection.

  1. Referee: [Section 5] Section 5 (Background estimation): The central no-excess and high-mass limit claims depend on the QCD multijet and ttbar background prediction matching data after all boosted-jet mass, top-tagger, and bb-tagger selections in the signal region. While sideband validation is referenced, the manuscript should include explicit quantitative agreement metrics or plots for the reconstructed resonance mass tail above 2 TeV in dedicated control regions (without full signal selection) to confirm the extrapolation does not bias the limit-setting procedure.

    Authors: We thank the referee for this constructive suggestion. While the current manuscript already references sideband validations, we agree that additional explicit documentation of the high-mass tail would further strengthen the presentation. In the revised manuscript we will add plots of the reconstructed resonance mass distribution above 2 TeV in dedicated control regions (defined by relaxing or removing the full signal-region selections on the top and bb taggers) together with quantitative agreement metrics, such as data-to-prediction ratios and associated uncertainties. These additions will explicitly demonstrate that the background extrapolation used for limit setting remains unbiased in the high-mass regime. revision: yes

Circularity Check

0 steps flagged

No circularity in data-driven limit extraction

full rationale

The paper's central results—no significant excess and 95% CL mass exclusions—are obtained by direct statistical comparison of observed data to background predictions in the signal region, with the background model constrained by simulation plus control-region data. This procedure contains no self-definitional steps, no fitted parameters renamed as predictions, and no load-bearing self-citation that reduces the claim to its own inputs. The combination with a prior CMS semileptonic search adds an independent channel rather than closing a loop. Background modeling accuracy is an external assumption subject to validation, not a circularity issue per the defined patterns.
