Branching ratios of the pseudoscalar glueball with a mass of 2.6 GeV
Abstract
We consider a Nf=3 chiral Lagrangian which describes the interaction between the pseudoscalar glueball, JPC=0-+, and scalar and pseudoscalar mesons. We calculate the decay widths of the pseudoscalar glueball, where we fixed its mass to 2.6 GeV, as predicted by lattice QCD simulations, and take a closer look in the scalar-isoscalar decaying channel. We present our results as branching ratios which are relevant for the future PANDA experiment at the FAIR facility.
