$p \Omega$ femtoscopy using baryon-baryon effective potentials

Abstract

We have generated an updated version of the $p\Omega$ potential for low-energy interactions based on an effective field theory approach at leading order. This potential, together with other potentials based either on different parametrizations or lattice QCD calculations, have been used to solve the Schr\"odinger equation numerically, obtaining the scattering wave functions for different values of the relative momentum. Using these wave functions, we have computed the $p \Omega$ femtoscopic correlation functions, comparing the results with those published by the ALICE collaboration.
