Categorizing resonances X(1835), X(2120) and X(2370) in the pseudoscalar meson family

Abstract

Inspired by the newly observed three resonances X(1835), X(2120) and X(2370), in this work we systematically study the two-body strong decays and double pion decays of $\eta (1295)/\eta (1475)$, $\eta (1760)/X(1835)$ and $X(2120)/X(2370)$ by categorizing $\eta (1295)/\eta (1475)$, $\eta (1760)/X(1835)$, X(2120) and X(2370) as the radial excitations of $\eta (548)/{\eta }^{\prime }(958)$. Our numerical results indicate the followings: (1) The obtained theoretical strong decay widths of three pseudoscalar states $\eta (1295)$, $\eta (1475)$ and $\eta (1760)$ are consistent with the experimental measurements; (2) X(1835) could be the second radial excitation of ${\eta }^{\prime }(958)$; (3) X(2120) and X(2370) can be explained as the third and fourth radial excitations of $\eta (548)/{\eta }^{\prime }(958)$, respectively.
