ALICE reports the first simultaneous multiplicity and m_T dependence of the femtoscopic source radius in pp collisions at 13.6 TeV, extracted assuming nucleon-nucleon interaction models and showing different multiplicity dependence than in Pb-Pb collisions.
Residual Coulomb and isospin effects produce charge-dependent splittings in identical-particle correlation functions, strongest at low kT, that modify fitted radii.
Simulations indicate that heavy-ion collisions enhance the visibility of charmed-meson femtoscopic correlations compared to pp collisions, providing a probe for exotic hadronic states.
Quark-exchange interactions at short distances dominate the coupled-channel scattering amplitudes for Zc(3900) over meson exchanges in an effective hadron-quark model.
Theoretical predictions show that femtoscopic correlation functions for neutral Σ_c^0 π^- pairs best constrain isotensor strong interactions in charm and bottom sectors, while Coulomb repulsion diminishes discriminating power in charged channels.
The universality assumption in the Koonin-Pratt formula for femtoscopic correlations introduces potentially large intrinsic uncertainty when extracting strong interactions between hadrons like nucleons.

Can the strong interactions between hadrons be determined using femtoscopy?
The universality assumption in the Koonin-Pratt formula for femtoscopic correlations introduces potentially large intrinsic uncertainty when extracting strong interactions between hadrons like nucleons.
