General information
The project aims to study QCD calculations for rare B-meson decays within the framework of the Standard Model. It is planned to perform calculations related to the renormalization of QCD corrections for the B->Xsγ decay for the physical value of the c quark mass, as well as to calculate QCD corrections for the B->Xsγγ decay. These calculations will enable improved predictions and allow for comparison with experimental data. Rare (weak) decays of B-mesons have been a focal point for both theorists and experimentalists due to the opportunities they offer for testing the Standard Model (SM) at energy scales of several hundred GeV. Experimental data on rare decays impose constraints on extensions of the SM or may lead to discrepancies with SM predictions, thereby providing evidence for the existence of “new physics.” To accurately compare theory with experiment, precise theoretical predictions are necessary. For these decays, strong interaction corrections provide significant contributions. In addition, the expectation values of the local physical characteristics of the vacuum state for a massive vector field in the anti-de Sitter space-time will be investigated in the presence of branes.
