Model description

We consider the effective interactions of a fermionic singlet dark matter particle with the SM hypercharge gauge boson field. The corresponding form factor operators up to dimension-6 are given by

for Majorana particles, indicated by χ, and by

for Dirac dark matter, denoted by ψ. The Cj are the dimensionless Wilson coefficients for the dimension-6 anapole moment (CA), for the dimension-5 the electric and magnetic dipole moments (Cel) and (CM) and for the dimension-6 charge radius operator (Ccr).

More information can be found in arXiv: [hep-ph].
