Abstract

Motivated by the continuous experimental investigations of X(1835)X(1835) in three-body decay channels like ηπ+π\eta^\prime \pi^+ \pi^-, we investigate the ηKKˉ\eta^\prime K \bar K system with the aim of searching for bound states and/or resonances when the dynamics involved in the KKˉK\bar K subsystem can form the resonances: f0(980)f_0(980) in isospin 0 or a0(980)a_0(980) in isospin 1. For this, we solve the Faddeev equations for the three-body system. The input two-body tt-matrices are obtained by solving Bethe-Salpeter equations in a coupled channel formalism. As a result, no signal of a three-body bound state or resonance is found.
