The study of exotic state Zc±(3900) decaying to J/ψ π± in the pp collisions at √s=1.96, 7, and 13 TeV

摘要

A dynamically constrained phase-space coalescence model and PACIAE model are used to predict the exotic resonant state Z(c)(+/-)(3900) yield in pp collisions at root s = 1.96,7 and 13 TeV, respectively, which are estimated to be around 10(-6) to 10(-5) based on the J/psi pi(+/-) bound state in the decay chain of b hadrons. The energy dependence of the transverse momentum distributions and rapidity distributions with |y
