Description
The framework of three-flavor neutrino oscillation is well-established from different experiments. However results from the short-baseline experiments, such as the Liquid Scintillator Neutrino Detector (LSND) and MiniBooster Neutrino Experiment (MiniBooNE), hint at the potential existence of an additional light neutrino state characterized by a mass-squared difference of approximately 1 eV^2. The new neutrino state is devoid of all Standard Model interactions, commonly referred to as a “sterile” state. This talk will summarize the current status in the search of the eV scale sterile neutrino and future experiments that can possibly resolve the issue. In addition the possibility of lighter sterile neutrinos and constraining the mass spectra in presence of such species from cosmology, neutrinoless double beta decay and measurement of absolute neutrino mass from beta decay experiments will also be discussed.
