According to the assumption that sterile neutrinos are right neutrinos, an analysis of the modern experimental situation in neutron decay for right-handed currents was carried out. As the result of the analysis, it was found that there is an indicati

In this work, we study the appearance of neutrino asymmetries during the expansion of the Universe. A mathematical model based on differential equations was used to describe the processes of neutrino oscillations considering CP violation and neutrino

Thermal and gas flow calculations of low-temperature part of the UCN source at WWR-M reactor are presented. The calculations were made on the basis of previously developed design documentation. Calculations show that the standard refrigerator Linde T

Joint analysis of the results of the Neutrino-4 experiment and the data of the GALLEX, SAGE and BEST experiments confirms the parameters of neutrino oscillations declared by the Neutrino-4 experiment $(\Delta m_{14}^2= 7.3 \text{eV}^2$ and $\sin^2 2\

The neutron's permanent electric dipole moment dn is constrained to below 3 × 10−26e cm (90% C.L.) [1, 2], by experiments using ultracold neutrons (UCN). We plan to improve this limit by an order of magnitude or more with PanEDM, the first experim

A Monte Carlo model was developed for our current neutron lifetime experiment using storage of ultracold neutrons (UCN) in a big gravitational trap. The model allows us to calculate neutron trajectories in the given geometry, taking into account grav

We propose an experiment to search for neutron–antineutron oscillations based on the storage of ultracold neutrons (UCN) in a material trap. This experiment will be competitive due to a new UCN source which is under construction at the NRC “Kurch

The WWR-M reactor at PNPI is planned to be equipped with a high-flux source for ultracold neutrons (UCNs). The method of UCN production is based on neutron conversion in superfluid helium, exploiting the particular qualities of that quantum liquid. A
