Particle Physics: Physics Beyond the Standard Model

Group theory is the mathematical tool to describe the symmetry. U(1)⊗SU(2)⊗SU(3) is the suitable description to the Standard Model (SM). Charge conjugation parity (CP) violation plays a privileged role in our quest for new physics beyond the electroweak Standard Model (SM). Supersymmetry (SUSY) is one of the most interesting candidates for physics beyond the SM. In supersymmetric extensions of the SM there are additional sources of CP violation. This Study analyzed the SM and supersymmetric contributions to CP-averaged branching fractions and the direct asymmetry of mesonic (B) decay processes within the framework of soft collinear effective theory.
