Measurement of the $W$ boson helicity fractions in $t\bar{t}$ events at $\sqrt s=$ 8 TeV in the lepton+jets channel with the ATLAS detector
Precise measurements of the properties of the top quark allow for testing the Standard Model (SM) and can be used to constrain new physics models. The top quark is predicted in the SM to decay almost exclusively to a $W$ boson and $b$-quark. Thus, studying the $Wtb$ vertex structure at high precisio...
