Description

We explore the ΔL=2 same-sign dilepton signal from top-quark decay via a Majorana neutrino at the LHC in the top anti-top pair production samples. The signature is same-sign dilepton plus multijets with no significant missing energy. The most optimistic region lies where the Majorana neutrino mass is between 15-65 GeV. For 300 fb-1 integrated luminosity, it is possible to probe Sij, the effective mixing parameter, to O(10-5).
