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.

abstract
The interaction of the low lying pseudo-scalar mesons with the ground state baryons in the charm sector is studied within a coupled channel approach using a t-channel vector-exchange driving force. The amplitudes describing the scattering of the pseudo-scalar mesons off the ground-state baryons are obtained by solving the Lippmann--Schwinger equation. We analyze in detail the effects of going beyond the $t=0$ approximation. Our model predicts the dynamical generation of several open charmed baryon resonances in different isospin and strangeness channels, some of which can be clearly identified with recently observed states.
