Interactions of the ${\chi }_{c1}(4274)$ state with light mesons

Abstract

We investigate the interactions of the ${\chi }_{c1}(4274)$ state with light mesons in the hot hadron gas formed in heavy ion collisions. The vacuum and thermally-averaged cross sections of production of ${\chi }_{c1}(4274)$ accompanied by light pseudoscalar and light vector mesons as well as the corresponding inverse processes are estimated within the context of an effective Lagrangian approach. The results suggest non-negligible thermal cross-sections, with larger magnitudes for most of the suppression reactions than those for production. This might be a relevant feature to be considered in the analysis of future data collected in heavy ion collisions.
