WebAug 21, 2014 · Download PDF Abstract: We consider a renormalizable extension of the standard model whose fermionic dark matter (DM) candidate interacts with a real singlet pseudo-scalar via a pseudo-scalar Yukawa term while we assume that the full Lagrangian is CP-conserved in the classical level. When the pseudo-scalar boson develops a non-zero …

Note that the one-point function of the scalar would be divergent (D= 3), but it vanishes because of the parity invariance of L. The same is true for the scalar three-point function with D= 1. 2.
