Thanks to their weakly-interacting nature, neutrinos traverse cosmic distances without being deflected. They can provide information about far astrophysical object as a complementary probe of the Universe with respect to other messengers such as multi-wavelength light, charged cosmic rays and gravitational waves. Here, an overview of the neutrino telescopes currently operating in the...
With the help of computer modelling, b-jets were identified under certain kinematical restrictions on the transverse momentum and pseudorapidity at the LHC with 14 TeV energy. The calculations were carried out in the framework of the MSSM model with the parameters determined from the latest experimental data. The selection of the most high-energy jets at the optimum value of their departure...
In tensor analysis we deal with tensor objects that are different in nature: scalars, vectors, tensors of rank n. When the basis (four non-collinear non-coplanar basis vectors) is introduced at each point of space-time, all these objects may be treated as the n-polylinear combinations of the basis vectors with scalar coefficients. This means that the variation of any Lagrangian with tensor...
The KArlsruhe TRItium Neutrino (KATRIN) experiment is a large-scale experiment with the objective to determine the effective electron anti-neutrino mass with an unprecedented sensitivity of 0.2 eV/c² at 90% C.L. in a model-independent way. The measurement method is based on precision $\beta$-decay spectroscopy of molecular tritium.
The experimental setup consists of a high luminosity...
