Resonant production of the fourth family slepton at the LHC

TL;DR

This paper investigates the potential to produce and detect a hypothetical fourth family slepton at the LHC through resonant processes involving R-parity violation, focusing on decay signatures and coupling constraints.

Contribution

It introduces a detailed analysis of fourth family slepton production and decay at the LHC, including signal characteristics and coupling constraints, which is a novel exploration in supersymmetry phenomenology.

Findings

Potential like-sign dimuon and dijet signals identified

Constraints on R-parity violating couplings derived for different LHC energies

Feasibility of detecting fourth family sleptons discussed

Abstract

The resonant production of the fourth family slepton ~l_4 via R-parity violating interactions of supersymmetry at the Large Hadron Collider has been investigated. We study the decay mode of ~l_4 into the fourth family neutrino nu_4 and W boson. The signal will be a like-sign dimuon and dijet if the fourth family neutrino has Majorana nature. We discuss the constraints on the R-parity violating couplings lambda and lambda' of the fourth family charged slepton at the LHC with the center of mass energies of 7, 10 and 14 TeV.
