CPT Student Seminar: Neutrinoless double beta decay within the Left-Right symmetric model: An update

Presented by Andres Olivares, Durham University

2 November 2015 17:00 in OC218

Neutrinos are one of the least understood particles within the Standard Model. The recent discovery of their massive nature raises the question of whether they are Dirac or Majorana particles. If massive neutrinos are Majorana particles, processes where total lepton number is violated will occur in nature. A particular relevant example of such processes is the neutrinoless double beta decay (0vbb) since it would confirm the Majorana nature of neutrinos.

Beyond the standard mechanisim that drives 0vbb some other exotic contributions arise if one considers alternatives to the SM. An attractive possibility is the Left-Right Symmetric Model (LRSM) which extends the SM electroweak gauge group and has rich phenomenology. In this talk, I will present the new contributions to 0vbb within the LRSM framework and update the limits on the new physics parameters introduced by this model using the latest released data.
