Resonant production of the fourth family slepton at the LHC

Understand

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.
