Potential signatures of dark matter at the Large Hadron Collider.

Framework for connecting neutrino masses with dark sector phenomenology.

Abstract

We consider a model of neutrino mass with a scalar triplet $(\xi^{++},\xi^+,\xi^0)$ assigned lepton number $L=0$, so that the tree-level Yukawa coupling $\xi^0 \nu_i \nu_j$ is not allowed. It is generated instead through the interaction of $\xi$ and $\nu$ with dark matter and the soft breaking of $L$ to $(-1)^L$. We discuss the phenomenological implications of this model, including $\xi^{++}$ decay and the prognosis of discovering the dark sector at the Large Hadron Collider.
