Investigation of exotic state X(3872) in pp collisions at $$\sqrt{s}=7$$, 13 TeV
Abstract We have used the dynamically constrained phase space coalescence model to study the production of the exotic state X (3872) based on the hadronic final states generated by the parton and hadron cascade model (PACIAE) with $$|y|<1$$ | y | < 1 and $$p_T < 15.5$$ p T < 15.5 GeV/c i...

X
