Abstract

New physics generally contains additional CP phases, and they appear in the interactions between the new EW-interacting fermions and the two Higgs doublets in our extended model. In this chapter, we discuss how the CP-violating interactions lead to producing the baryon asymmetry based on closed time path formalism.

Notes

  1. 1.

    This statement is also mentioned in Ref. [5].

  2. 2.

    Here, the conserved quantity corresponds to a particle number.

  3. 3.

    Free propagator for fermion satisfies

    where

  4. 4.

    We take Q = −1.

  5. 5.

    There is no number density of the singlet in H(X) since it vanishes due to the real field.
