First limit on inclusive decay and constraints on new physics
Yuval Grossman, Zoltan Ligeti, Enrico Nardi
The inclusive decay rate, on which no experimental bound exists to date, can be constrained by searching for large missing energy events in decays. Carefully…
Top-Charm flavor changing contributions to the effective vertex
Enrico Nardi
We analyze the effects of a tree level flavor changing vertex induced by a mixing with new isosinglet quarks, on the effective vertex. We compute the contributi…
Supersymmetry without R-Parity and without Lepton Number
Tom Banks, Yuval Grossman, Enrico Nardi +1
We investigate Supersymmetric models where neither R parity nor lepton number is imposed. Neutrino masses can be kept highly suppressed compared to the electroweak scale if the …
Realistic SUSY model with four fermion families, natural R parity and in the eV Range
Zurab Berezhiani, Enrico Nardi
We study an extension of the supersymmetric standard model with four families and gauged horizontal symmetry , in which R parity automatically follows as a consequence of…
