Standard Model anatomy of WIMP dark matter direct detection I: weak-scale matching

Understand

We present formalism necessary to determine weak-scale matching coefficients in the computation of scattering cross sections for putative dark matter candidates interacting with the Standard Model.

• Particular attention is paid to the heavy-particle limit.
• A consistent renormalization scheme in the presence of nontrivial residual masses is implemented.
• Two-loop diagrams appearing in the matching to gluon operators are evaluated.
