CP violation in the extended Standard Model with a complex singlet

Presented by Mrs. Neda DARVISHI


We construct the scalar potential of the Standard Model with an additional singlet scalar field (SMS), assuming an exact Z2 symmetry, where the singlet is Z2-even. To simplify the model we use a softly broken U(1) symmetry, which allows a reduction of the number of free parameters in the potential. Additional CP violating phase can appear if a complex singlet with a non-zero vacuum expectation value is added to the scalar sector of the SM. We study the masses of scalar particles, gauge couplings and fermionic sector.
