Light sterile neutrinos, dark matter, and new resonances in a $U(1)$ extension of the MSSM

A. Hebbar, G. Lazarides, Q. Shafi

We present ${\psi }^{\prime }$MSSM, a model based on a $U(1{)}_{{\psi }^{\prime }}$ extension of the minimal supersymmetric standard model. The gauge symmetry $U(1{)}_{{\psi }^{\prime }}$, also known as $U(1{)}_N$, is a linear comb…
