Description
Summary:In this work, we present an updated study about the interactions of quarkonia with surrounding hadronic medium. The meson–meson interactions are described with a chiral effective Lagrangian within the framework of unitarized coupled channel amplitudes. In particular, we extend a previous work performed in the charmonium sector by calculating the cross-sections for Υ scattering by light pseudoscalar mesons ( π , K , η ) and vector mesons ( ρ , K ∗ , ω ). We evaluate the relevant channels and compare the results with existing literature. The analysis is completed by including the finite-temperature effects in the unitarized scattering amplitudes for both quarkonium and bottomonium sectors.
