Abstract: |
SUSY induces Parity Violation (PV) in QCD process through quark-squark-gluino interaction with non-degenerate spectrum between left- and right-handed squarks. In the SM QCD, of course there is no PV. However, if SUSY exists, PV can appear via squark loop contributions in QCD process. At first, I will talk about PV caused by SUSY in helicity dependent top quark pair production at the LHC, and also show a possibility to discriminate SUSY from other new physics candidates (extra dimension and Little Higgs model). Next, I will discuss parity non-conserving decay of heavy meson via SUSY, in particular, consider a decay of \eta_c to two \pi. Finally, I will explain a trial to obtain a left-right non-degeneracy bound of \tilde{u} and \tilde{d} from nucleon interactions. |
