Studying the pΛ interaction in small collision systems using a common emission source — •Jaime Gonzalez and Dimitar Mihaylov — Technical Unverisity of Munich

This work introduces a new framework (CECA) to model the source function that represents the spatial and kinematic properties of a particle emission in small collision systems. The properties of the source have been fixed within CECA by using an existing ALICE measurement of the pp source size in pp collisions. Under the assumption of a common source, a simulation of the kinematic properties of the pΛ system is performed and compared to existing measurements. Utilizing several parameterizations of the chiral effective field theory, used to model the pΛ interaction, allowed to study the properties of the hyperon-nucleon interaction, which is an important ingredient for the nuclear Equation of State and the modeling of the structure of neutron stars.
