Observation of the ${\rm B_c^+}$ meson in PbPb and pp collisions at $\sqrt{s_{\rm NN}}=5.02~\mathrm{TeV}$
The ${\rm B_c^+}$ meson is observed with the CMS detector in proton-proton and lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}}=5.02~\mathrm{TeV}$, via the ${\rm B_c^+} \rightarrow ({\rm J}/\psi \rightarrow \mu^+ \mu^-) \mu^+ \nu_\mu$ decay. Its cross section an...
