D. Samart, Y. Yan, Th. Gutsche, Amand Faessler
TL;DR
This paper evaluates the decay widths of X(1835) assuming it is a nucleon-antinucleon bound state, identifying dominant decay channels and suggesting experimental searches in specific channels.
Contribution
It provides the first detailed calculation of X(1835) decay widths within the 3P0 quark model assuming a nucleon-antinucleon bound state structure.
Findings
Decays to rho+rho, omega+omega, and pion+a0(1450) dominate.
Branching fractions for J/psi to pion+pion+eta and eta' are similar.
X(1835) may be searched in the pion+a0(1450) channel.
Abstract
Partial decay widths of various decay channels of the X(1835) are evaluated in the 3P0 quark model, assuming that the X(1835) is a nucleon-antinucleon bound state. It is found that the decays to rho+rho, omega+omega and pion+a0(1450) dominate over other channels, and that the product branching fractions of J/psi to pion+pion+eta and J/psi to pion+pion+eta' are in the same order. We suggest that the X(1835) may be searched in the pion+a0(1450) channel.
