Top quark polarization and asymmetries at the LHC in the effective description of squark interactions
Resumen: Adetailed study of top-quark polarizations and t¯t charge asymmetries, induced by top-squark-pair production at the LHCand the subsequent decays ˜t ¿ t ˜¿ 0 1 , is performed within the effective description of squark interactions, which includes the effective Yukawa couplings and another logarithmic term encoding the supersymmetry breaking. This effective approach is more suitable for its introduction into Monte-Carlo simulations and we make use of its implementation in MadGraph in order to investigate the possibilities of the charge asymmetry AC, measured at the LHC and consistent with SM expectations, to discriminate between different SUSY scenarios and analyze the implications of these scenarios in the top polarizations and related observables.
