Bilepton contributions to the neutrinoless double beta decay in the economical 3-3-1 model
- VAST, Institute of Physics (Viet Nam)
A new bound of the mixing angle between charged gauge bosons (the standard-model W and the bilepton Y) in the economical 3-3-1 model is given. Possible contributions of the charged bileptons to the neutrinoless double beta (({beta}{beta}){sub 0{nu}}) decay are discussed. We show that the ({beta}{beta}){sub 0{nu}} decay in this model is due to both the Majorana <M{sub {nu}}>{sub L} and Dirac <M{sub {nu}}>{sub D} neutrino masses. If the mixing angle is in the range of the ratio of neutrino masses <M{sub {nu}}>{sub L}/<M{sub {nu}}>{sub D}, the Majorana and Dirac masses are comparable to each other and both may give the main contribution to the decay. As a result, constraints on the bilepton mass are given.
