Abstract. The existence of massive neutrinos forces the extension of the Standard Model of electroweak interactions, to accommo-date them and/or right-handed currents. This is one of the fundamental questions in todays?s physics. The consequences of it wouldreflect upon several decay processes, like the very exotic nuclear double-beta-decay. By the other hand, high-energy proton-protonreactions of the type performed at the LHC accelerator can provide information about the existence of a right-handed generationof the W and Z-bosons. Here we shall address the possibility of performing a joint analysis of the results reported by the ATLASand CMS collaborations (σ(pp− > 2l + jets)) and the latest measurements of nuclear-double-beta decays reported by the GERDAand EXO collaborations.
