Large Hadron Collider probe of supersymmetric neutrinoless double beta decay mechanism

Understand

In the minimal supersymmetric extension to the Standard Model, a non-zero lepton number violating coupling lambda'_111 predicts both neutrinoless double beta decay and resonant single slepton production at the LHC.

• We show that, in this case, if neutrinoless double beta decay is discovered in the next generation of experiments, there exist good prospects to observe single slepton production at the LHC.
• Neutrinoless double beta decay could otherwise result from a different source (such as a non-zero Majorana neutrino mass).
• Resonant single slepton production at the LHC can therefore discriminate between the lambda'_111 neutrinoless double beta decay mechanism and others.
