Phenomenology of the pseudoscalar glueball with a mass of 2.6 GeV

Abstract

We calculate the branching ratios of the lightest pseudoscalar glueball with a mass of 2.6 GeV predicted by lattice QCD by using a chiral Lagrangian. This study is relevant in view of the planned PANDA experiment at the upcoming FAIR facility, which will measure the energy range in which the pseudoscalar glueball is predicted to exist.
