Electroweak Baryogenesis and the Standard Model

Electroweak baryogenesis is addressed within the context of the standard model of particle physics. Although the minimal standard model has the means of fulfilling the three Sakharov's conditions, it falls short to explaining the making of the baryon asymmetry of the universe. In particular, it is demonstrated that the phase of the CKM mixing matrix is an insufficient source of {\it CP} violation. The shortcomings of the standard model could be bypassed by enlarging the symmetry breaking sector and adding a new source of {\it CP} violation.
