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 scattering by light pseudoscalar mesons () and vector mesons (). 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.
