Single sneutrino production at hadron colliders

Abstract

We study the production of a single sneutrino in association with one or two $b$-quarks at hadron colliders, in the framework of an R-parity violating supersymmetric model. We find that at the Large Hadron Collider (LHC) four $b$ final states are promising with efficient b-tagging. $l^+l'^-$ decay modes of the sneutrino can also be viable for detection at the LHC. However, the branching ratio for rare $γγ$ decay channel is too small to be seen.
