$\Lambda$ - anomaly in the hadron chemical freeze-out

High Energy Physics - Phenomenology 2014-08-27 v1 Nuclear Theory

Abstract

A new way to overcome the Λ\Lambda hyperon selective suppression, which is known as the Λ\Lambda-anomaly, has been suggested. In particular, the additional radius of a Λ\Lambda hyperon is introduced into the model of hadron resonance gas with the multicomponent hard-core repulsion. The proposed approach allows one to describe the hadron multiplicity ratios measured at the AGS, SPS and RHIC energies with the accuracy χ2/dof=\chi^{2}/dof=52/55\simeq 0.95.
