Popis: Abstract We study the collider phenomenology of a simplified model containing a right-handed W in which the W R couples predominantly to the third generation in the quark sector. The model also includes a light Majorana neutrino, with M 1 ∼ O 100 $$ \mathcal{O}(100) $$ GeV, giving rise to lepton-number-violating signatures that are visible at the LHC. Taking into account all the searches from the LHC and Tevatron, we find that this W R can still be as light as M R ∼ 300 GeV. We show that this type of new physics, and others like it, can be detected at the LHC using final states with three same-sign same-flavour leptons.
