A supersymmetricSp L(6) ×U Y(1) model

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

A supersymmetricSp L(6)×U Y(1) model (SUSYSp(6)) is proposed as an extension of the standard electroweak model. The model is applied in a phenomenological study of B 0d \(\overline b \) 0d mixing. It is found that the supersymmetric (SUSY) partner z of the extra Z′ can significantly cancel the other contributions to bring the mixing parameterx d within the experimentally allowed range 0.57≲x d≲0.77 for a top mass of 158≲m t≲194 GeV. Other interesting and possibly novel features of flavor-changing neutral currents (FCNC) in SUSY theories with horizontal gauge symmetries are pointed out.
