Big Bang nucleosynthesis (BBN) theory predicts the abundances of the light elements D, $^3$He, $^4$He and $^7$Li produced in the early universe. The primordial
abundances of D and $^4$He inferred from observational data are in good agreement with predictions, however, the BBN theory overestimates the primordial $^7$Li
abundance by about a factor of three. This is the so-called ``cosmological...

The neutrino flavour evolution in a supernova can be described either in terms of neutrino fields or as the evolution of individual neutrinos. There is no reason to think that the two approaches should give contradicting results, and both have their advantages. One of the advantages of using individual neutrinos is that it becomes clear that the finite width of the neutrino sphere must lead to...

We study how sterile neutrino with keV mass can be a dark matter candidate by proposing a new mechanism for the production of sterile neutrino in early universe. By estimating the average momentum of the sterile neutrino, we investigate whether sterile neutrinos can be warm dark matter or not. We briefly discuss how sterile neutrinos can be probed indirectly by using X-ray telescopes that can...

Hyper-Kamiokande (Hyper-K) succeeds the very successful Super-Kamiokande (Super-K) as a future water Cherenkov neutrino detector which will consist of two 260 kilo-ton water tanks with 40,000 photo-sensors per tank deep underground. The 1st detector will be built in Japan and the collaboration is considering to build the 2nd detector in Korea.
Thanks to longer baseline and deeper candidate...
