The corresponding form factor operators up to dimension6 are given by21 We consider the effective interactions of a fermionic singlet dark matter particle with the SM hypercharge gauge boson field. The only non zero form factor operator for Majorana dark matter is the dimension6 anapole moment, while for Dirac dark matter there exist the dimension5 magnetic and electric dipole operators and the dimension6 anapole and charge radius operators. 22 22 23 24 for Majorana particles, indicated by χ, and by 25 26 27 for Dirac dark matter, denoted by ψ. The Cj are the dimensionless Wilson coefficients for the dimension6 anapole moment (CA), for the dimension5 the electric and magnetic dipole moments (Cel) and (CM) and for the dimension6 charge radius operator (Ccr). 28 29 More information can be found in arXiv: [hepph]. 23 The detailed Lagrangian and more information can be found in arXiv:2005.XXXXX [hepph]. 30 24 31 25
