Evidence for X(3872) in PbPb collisions and studies of its prompt production at $\sqrt{{s_{_{\mathrm{NN}}}}}=5.02$ TeV
The first evidence for X(3872) in heavy ion collisions is reported. Prompt X(3872) production is studied with the CMS detector in PbPb collisions at a center-of-mass energy of $\sqrt{{s_{_{\mathrm{NN}}}}} = 5.02$ TeV per nucleon pair, using the decay chain X(3872)$\rightarrow {\rm J}/\psi\pi^+\pi^-\...
