Probing non-standard top-quark couplings via optimal-observable analyses at LHC

Focusing attention on top-quark pair production and its decay processes at the LHC, non-standard top-quark couplings are studied based on the effective Lagrangian constructed with SU(3) x SU(2) x U(1) invariant dimension-6 operators. The optimal-observable analysis is carried out for the charged-lep...

Summary:Focusing attention on top-quark pair production and its decay processes at the LHC, non-standard top-quark couplings are studied based on the effective Lagrangian constructed with SU(3) x SU(2) x U(1) invariant dimension-6 operators. The optimal-observable analysis is carried out for the charged-lepton distributions in pp arrow right ttX arrow right l +X' (l = e or mu ) in order to estimate the expected statistical uncertainties in measurements of those non-standard ttg and tbW couplings that contribute to this process in the leading order.
