The Right Side of Tev Scale Spontaneous R-Parity Violation

Abstract

We study a simple extension of the minimal supersymmetric Standard Model in which the Abelian sector of the theory consists of B-L and right-handed isospin. In the minimal model this Abelian gauge structure is broken to the standard model hypercharge gauge group by non-vanishing vacuum expectation values of the right-handed sneutrinos, resulting in spontaneous R-parity violation. This theory can emerge as a low energy effective theory of a left-right symmetric theory realized at a high scale. We determine the mass spectrum of the theory, and discuss the generation of neutrino masses and R-parity violating interactions. The possibility of distinguishing between R-parity violating models with a gauged B-L broken at the TeV scale at the Large Hadron Collider is discussed.
