Interaction operators for fermionic WIMP of 6-dimensional Effective Field Theory in tree level, which contains four-fermion interactions and vector, scalar, fermion interactions, are implemented.

For 6-dimensional EFT, fermionic DM is a SM gauge singlet and odd under global Z2 symmetry. The tree level interactions between this fermionic DM and SM particles can be chosen as the Lagrangian form of the operators given [1,2,3]
