Description
We argue that a confirmation of a claim of observation of neutrinoless beta decay,
in connection with constraints with cosmology, disfavours the standard mechanism
due to Majorana neutrino mass. This implies a presence of new physics contribution
near the TeV scale, which can relieve this tension and at the same time has a chance
to be tested at the LHC. We discuss new contributions in the context of the minimal
left-right symmetric model and show how they are related to the observables at the
LHC. As a proof of concept, we demonstrate how the most recent data from the CMS
in the two lepton and two jets channel puts a limit on the mass of the right-handed
gauge boson. Despite a fairly low luminosity, we obtain a bound on W_R around
1.4 TeV in a large portion of parameter space where the right-handed neutrino mass
is on the order of 100 GeV.
