Subtle problems in the theory of neutrino oscillations in vacuum are discussed [1]. It is shown that Lorentz invariance implies that in general flavor neutrinos in oscillation experiments are superpositions of massive neutrinos with different energies and different momenta. It is argued that a wave packet description of massive neutrinos is necessary in order to understand the physics of neutri...

The processes of the photon and electron–positron pair production by a neutrino propagating in a strong magnetic field are investigated in the framework of the Standard Model. The process probabilities and the mean values of the neutrino energy and momentum loss are calculated. Possible astrophysical manifestations of the processes considered are briefly analysed. Talk given at the 9th Internat...

The goal is to monitor human methorchiasis and carnivores as an epidemic sanitary hygienic threat the population of southern subject Russian Federation.When analyzing materials on incidence methorchosis in dogs Kabardino-Balkaria Republic, it turned out that 12 districts rate varied from 5.6 15.9%. gradation abundance index trematode Metorchis albidus eggs dog feces ranged 2.9t0.5 7.070.8 ind. ...

In this lecture we review several cosmological issues associated with the axion. Axion solves the strong CP problem and is a good candidate for the dark matter. Limits, which are imposed by the value of isocurvature fluctuations fraction in the observed CMBR from WMAP data and the domain wall problem are discussed in a supersymmetric flat direction axion model. This lecture was given at XII’th ...

The Kabardino-Balkarian Republic (KBR) has civil society institutions that have become active actors in public life. COVID-19 pandemic caused a significant change the way of holding annual history and culture related festivities mourning ceremonies, which were taking place online via social networks.
