Coupled-channel effects in meson-baryon correlation functions

Traditionally, the determination of two-particle momentum correlations in relativistic heavy ion collisions has been viewed as a tool to explore the space-time evolution of the emitting. However nowadays the precise experimental data and new theoretical techniques, the so called femtoscopy, allow the possibility to go further and to extract information about the interaction between these two particles. In this project we will perform theoretical simulations in the framework of chiral models with unitarization imposed in coupled channels, and we will concentrate on the influence of coupled-channel effects on the two-particle momentum correlation function [1]. As a first step we will study systems like pp or K+p, which are ideal for testing and applying the femtoscopic techniques, because there is only a single S -wave state where strong correlations are expected to occur for low momenta and the thresholds of other channels are far away from the energy region of interest [1].
