Quarkonium interactions with (hot) hadronic matter

In this work, we present an updated study about the interactions of quarkonia with surrounding hadronic medium. The meson-meson are described a chiral effective Lagrangian within framework unitarized coupled channel amplitudes. particular, extend previous work performed in charmonium sector by calculating cross-sections for $\Upsilon$ scattering light pseudoscalar mesons ($\pi, K, \eta$) and vector ($\rho, K^\ast, \omega$). We evaluate relevant channels compare results existing literature. analysis is completed including finite-temperature effects amplitudes both quarkonium bottomonium sectors.
