Search Talks

In the current epoch of neutrino physics, many experiments are aiming for precision measurements of oscillation parameters. Thus, various new physics scenarios which alter the neutrino oscillation probabilities in matter deserve careful investigation. Recent results from NOvA and T2K show a slight tension on their reported values of the CP violating phase $\delta_{CP}$, which may hint towards the possible role of New Physics. The upcoming long-baseline experiments DUNE and T2HK not only perform precision neutrino measurements but also possibly unveil new interactions and symmetries beyond those predicted in the Standard Model. In this context, I will discuss the exploration of some of the popular beyond the Standard Model scenarios with the current and the upcoming neutrino oscillation experiments.

The mass and nature of neutrinos play an important role in theories beyond the standard model. The nuclear beta decay and double beta decay can provide the information on absolute effective mass of the neutrinos. At present, neutrinoless double beta decay (NDBD) is perhaps the only experiment that can tell us whether the neutrino is a Dirac or a Majorana particle. Given the significance of the NDBD, there is a widespread interest worldwide employing a variety of novel techniques. This talk will present a brief report of ongoing and proposed NDBD experiments and will highlight Indian efforts towards the feasibility study of search for NDBD in 124Sn.

I will first discuss how neutrino detectors such as SNO, SNO+, BOREXINO and MAJORANA Demonstrator can be repurposed to perform direct detection of dark matter in the Galactic halo via scattering and/or absorption. Then I will describe how "neutron shining through a wall" searches can be performed to smoke out dark sectors in neutrino facilities such as IsoDAR, COHERENT, SNS, and STEREO.
