Multiplicity-dependent modification of $\chi_{c1}(3872)$ and $\psi{(2S)}$ production in $pp$ collisions at $\sqrt{s}$= 8 TeV
In $pp$ collisions at $\sqrt{s}$ = 8 TeV, $\chi_{c1}(3872)$ and $\psi{(2S)}$ states are produced promptly at the primary collision vertex or in decays of $b$~hadrons. We study their relative production rates as a function of particle multiplicity. The fraction of promptly produced states is found...
