     21We 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 dimension-6 anapole moment, while for Dirac dark matter there exist the dimension-5 magnetic and electric dipole operators and the dimension-6 anapole and charge radius operators.
