The pp -> lljj process is analysed assuming right-handed currents and heavy Majorana neutrinos. We discuss dependence of the cross section sigma(pp -> lljj) on the ratio gR/gL of right and left gauge couplings. Estimation of the signal strength is given for root s = 8 TeV and 14 TeV with gR/gL = 0.6 and gR/gL = 1.
