X(1835): A Natural Candidate of ${\eta }^{\prime }$'s Second Radial Excitation

Abstract

Recently BES collaboration observed one interesting resonance X(1835). We point out that its mass, total width, production rate and decay pattern favor its assignment as the second radial excitation of ${\eta }^{\prime }$ meson very naturally.
