Production of the ${\eta }_1(1855)$ through kaon induced reactions under the assumptions that it is a molecular or a hybrid state

Abstract

By the reaction of kaon interacting with a proton, we investigate the production of the newly observed ${\eta }_1(1855)$ predicted in the picture of the $K{\bar{K}}_1(1400)$ molecular state and hybrid state. The total and differential cross sections of the concrete $K^{-}p\to {\eta }_1(1855)\Lambda$ reaction are calculated. Taking the partial decay width of the ${\eta }_1$ to $K{\bar{K}}^{\ast }$ as 0.9 MeV and 98.1 MeV, the minimum cross section of the ${\eta }_1(1855)$ production via the $K^{-}p$ reaction can reach up 0.59 $nb$ and 63.8 $nb$ at the center of mass energies $W\simeq 3.5$ GeV, respectively. The differential cross sections for the ${\eta }_1(1855)$ production at the different center of mass energies are also available. Furthermore, we present the Dalitz processes of $2\to 3$ and $2\to 4$, and initially discuss the feasibility of finding out the ${\eta }_1(1855)$ in experiments like J-PARC.
