The two-particle momentum correlation function of a K^-p pair from high-energy nuclear collisions is evaluated in the KbarN-piSigma-piLambda coupled-channels framework. The effects of all coupled channels together with the Coulomb potential and the threshold energy difference between K^-p and Kbar0 n are treated completely for the first time. Realistic potentials based on the chiral SU(3) dynamics are used which fit the available scattering data. The recently measured correlation function is found to be well reproduced by allowing variations of the source size and the relative weight of the source function of piSigma with respect to that of KbarN. The predicted K^-p correlation function from larger systems, which is less affected by the piSigma source function, indicates that the investigation of its source size dependence is useful in providing further constraints in the study of the KbarN interaction.

  1. Quantum interference effects enhanced in $\pi^+p$ femtoscopic correlation functions

    hep-ph 2026-07 conditional novelty 7.0 of 10

    The π⁺p correlation peak near 140 MeV/c arises from quantum interference of incident and scattered waves, while the Δ decay peaks near 220 MeV/c; their m_T-dependent mix explains the ALICE peak shift.

  2. Spectroscopic and femtoscopic insights into vector-baryon interactions in the strangeness $-1$ sector

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The authors predict three Lambda* and two Sigma* resonances from vector-baryon interactions and provide femtoscopy correlation functions for six channels in the S=-1 sector.

  3. Probing the structure of the $D_{s 0}^*(2317)$ and $X(3872)$ states through correlation functions

    hep-ph 2025-06 conditional novelty 6.0 of 10

    Femtoscopic correlation functions for D0K+ and D0Dbar*0 pairs are predicted to be sensitive to the molecular versus bare-state composition of D_s0*(2317) and X(3872).

  4. Finding Low Star Discrepancy 3D Kronecker Point Sets Using Algorithm Configuration Techniques

    cs.NE 2026-04 unverdicted novelty 5.0 of 10

    Optimizing the two Kronecker parameters with irace yields new state-of-the-art L∞ star discrepancy for 3D point sets of size at least 500 and for ranges of sizes.

  5. Correlation functions for $n\,\bar{D}_{s1}(2460)$ and $n\,\bar{D}_{s1}(2536)$

    hep-ph 2025-08 conditional novelty 5.0 of 10

    The neutron-D_{s1}(2460) and neutron-D_{s1}(2536) systems are predicted to have bound states, with correlation functions sensitive to the molecular structure of the D_{s1} mesons.
