Measurement of the top-quark pair production cross-section in $pp$ collisions at $\sqrt{s} = 7$ TeV using final states with an electron or a muon and a hadronically decaying $\tau$-lepton
The $t$-quark is the heaviest elementary particle observed so far (172.9$\pm$1.5 GeV). Owing to its largest mass, the $t$-quark is believed to have a strong connection with physics beyond the Standard Model (SM). It is thus essential to understand the production and the decay process of the $t$-quar...
