Evidence for four-top quark production in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

The production of four top quarks ($\mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}}$) is studied with LHC proton-proton collision data samples collected by the CMS experiment at a center-of-mass energy…
