摘要

Emerging new physics frameworks have been introduced in the domain of neutrino physics to provide a detailed perspective of the neutrino mass matrix’s texture. This paper analyzes the neutrino mass matrix within the theoretical framework of the left-right symmetric model and its varying phenomenological consequences, based upon existing neutrino oscillation data. The structure of the neutrino mass matrix is realized using the symmetry groups \(D_4\) and \(Z_2\). This study concentrates on the new physics contributions to neutrinoless double beta decay, a highly sensitive experiment capable of verifying the intrinsic nature of neutrinos, whether they are Dirac or Majorana, while also offering new perspectives into the absolute neutrino mass scale and the underlying mechanisms of neutrino mass generation. Our study involves examining normal as well as inverted mass ordering of neutrino mass.
