Evidence for $\chi_{c1}$(3872) in PbPb collisions and studies of its prompt production at $\sqrt{\smash[b]{s_{_{\mathrm{NN}}}}}=5.02$ TeV
The first evidence for $\chi_{c1}$(3872) in relativistic heavy ion collisions is reported. Prompt $\chi_{c1}$(3872) production is studied in PbPb collisions at a center-of-mass energy of $\sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = 5.02$ TeV per nucleon pair, using the decay chain $\chi_{c1}$(3872)$\righ...
