eta(1405) in a chiral approach based on mixing of the pseudoscalar glueball with the first radial excitations of eta and eta'

Abstract

The supernumerous eta(1405) is considered a strong candidate for the pseudoscalar glueball. In a phenomenological chiral approach, we consider a mixing scenario of bare pseudoscalar (n bar n) and (s bar s) quarkonia with the glueball. We study the decay properties and point out the peculiarities of this scenario in order to support the possible identification of the J(PC) = 0(-+) glueball.
