On the Origin of Neutrino Mass: Neutrinoless Double Beta Decay

Manimala Mitra

IISER Mohali

A series of outstanding experiments have established the fact that standard model neutrinos have masses and very particular mixings. One of the attractive mechanism to explain the tiny masses of the neutrinos is Seesaw. In this talk, I will discuss about the origin of neutrino masses in beyond standard model theories and the testability of these theories in experimental searches, in particular neutrinoless double beta decay and collider search. One of the most interesting search process is lepton number violating search at non-collider and collider experiments, that can probe the Majorana nature of the light or heavy neutrinos. I will discuss different contributions in neutrinoless double beta decay that can arise from beyond standard model theories, such as, sterile neutrino, Left-Right symmetric model and others and discuss the correlation of neutrinoless double beta decay with collider searches. In addition, I will also discuss the possibility to probe Seesaw through Higgs searches at LHC.
