Resonant production of Sbottom via RPV couplings at the LHeC

Abstract

Resonant production of scalar bottom, which is allowed in R-parity violating interactions of supersymmetry, has been investigated at the Large Hadron Electron Collider (LHeC). Although searching for the physics beyond the standard model is a primary task of the Large Hadron Collider (LHC) program, recently, an e ⁻ p collider (LHeC) was proposed to complement and resolve the observation of new phenomena at the TeV scale. In this paper, we address the prospects of improving constraints for $\hat L\hat Q\hat D$ couplings λ′ _ijk through the process $e^ - + p \to \tilde b^* \to \mu ^ - + \bar q$ , where q denotes up-type quarks. We show that constraints on λ′ _ijk can be improved up to 10⁻³ for a 1 fb ⁻¹ integrated luminosity at a confidence level 95% with the 60 GeV e ⁻ beam option of the LHeC.
