| contents | Neutrinos, being elusive subatomic particles having only weak interactions, provide an ideal platform to look for physics beyond the Standard Model. In the present era of neutrino physics, various experiments are focusing towards the precision measurements of the oscillation parameters. Hence, various new physics scenarios which can affect the neutrino oscillation probabilities in matter, be in need of careful investigation. There is a slight tension at the level of $2 σ$ between the recently reported results on the CP violating phase $δ_{CP}$ by NOvA and T2K experiments, which can be attributed to the role of non-standard interactions (NSIs) in the propagation of neutrinos through matter. Another interesting possibility is that though neutrinos are electrically neutral, they can possess electromagnetic properties such as electric and magnetic dipole moments in the presence of new physics, and the neutrino oscillation experiments can put limits on them. In this work, we will focus on these two aspects and show how they can be used to probe the nature of new physics from model-building perspectives. |
