The study of exotic state $Z_c^{\pm }(3900)$ decaying to $J/\psi {\pi }^{\pm }$ in the $pp$ collisions at $\sqrt{s}$ = 1.96, 7, and 13 TeV

Abstract

A dynamically constrained phase-space coalescence model plus PACIAE model was used to predict the exotic resonant state $Z_c^{\pm }(3900)$ yield, transverse momentum distribution, and the rapidity distribution with $|y|<6$ and $p_T<10$ GeV/c in $pp$ collisions at $\sqrt{s}=1.96,7$ and 13 TeV, respectively. The yield of the $Z_c^{\pm }(3900)$ is estimated to be around $10^{-6}$ to $10^{-5}$. We also present the energy dependence of the transverse momentum distributions and rapidity distributions for $Z_c^{+}(3900)$ and $Z_c^{-}(3900)$. The production of $Z_c^{+}(3900)$ and its anti-particle $Z_c^{-}(3900)$ is found to be quite similar to each other.
