Addressing μ-b_μand proton lifetime problems and active neutrino masses in a U(1)^\prime-extended supergravity model

R. S. Hundi, Sandip Pakvasa, Xerxes Tata

We present a locally supersymmetric extension of the minimal supersymmetric Standard Model (MSSM) based on the gauge group $SU(3{)}_C\times SU(2{)}_L\times U(1{)}_Y\times U(1{)}^{\prime }$ wh…
