Single sneutrino production at hadron colliders

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.

Radion and Higgs mixing at the LHC

We study the resonance production of radions and Higgs via gluon-gluon fusion in the Randall-Sundrum model with Higgs-curvature mixing at the LHC. We find that radion can be detected both in mixed (with Higgs boson) and unmixed case if the radion vacuum expectation value $Λ_ϕ$ is around 1 TeV. The $Λ_ϕ\sim 10$ TeV case is also promising for certain values of mixing parameters and radion masses. The mixing can affect the production and decay of Higgs boson in a significant way. Thus Higgs search strategies at the LHC may need refinements in case of radion-Higgs mixing in the Randall-Sundrum model.
