abstract

The femtoscopic $\phi N$ correlation function is studied within a hadronic effective Lagrangian approach with coupled channels, based on hidden local symmetry. The results are compared with the data recently reported by the ALICE collaboration. We find that the correlation function has very different features for the $\phi N$ system in the spin 1/2 and 3/2 configurations, with the spin-averaged combination matching well with the experimental data. A strong attraction, leading to the formation of a $\phi N$ bound state or a very prominent cusp is found in the spin 3/2 case. The correlation function for spin 1/2, on the other hand, is strongly impacted by the negative parity $N^*(1895)$ nucleon resonance.

  1. Polarization-dependent mass modifications of $\phi$ meson with finite momentum in nuclear matter

    hep-ph 2026-03 conditional novelty 6.0 of 10

    In nuclear matter, the phi meson's longitudinal polarization mass decreases quadratically with momentum; the transverse polarization mass stays constant.

  2. Signatures of Odd-Parity $s$-wave $\Xi^*$ States in Femtoscopic Correlation Functions

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Using a unitarized hidden-gauge model, the authors dynamically generate Xi(1950)-like and Xi(2120)-like poles and predict femtoscopic correlation functions for six vector-baryon channels.

  3. Nature of the newly found $\Omega(2109)$

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Coupled-channel calculations in K- Ξ0, K̄0 Ξ-, K*- Ξ0 and K̄*0 Ξ- channels generate an isoscalar 1/2- resonance at 2109 MeV strongly correlated with the K̄* Ξ system.

  4. 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.
