Evidence for top quark production in nucleus-nucleus collisions
Using $1.7 \pm 0.1\,\mathrm{nb}^{-1}$ of lead-lead ($A = 208$) collision data recorded by the CMS experiment at a nucleon-nucleon center-of-mass energy of 5.02 TeV, we report evidence of top quark pair ($\mathrm{t\bar{t}}$) production. The $\mathrm{t\bar{t}}$ cross section ($\sigma_{\mathrm{t\bar{t}...
