I will present the effective field theory for dark matter interactions with the visible sector that is valid at
scales of O(1 GeV). Starting with an effective theory describing the interactions of fermionic and scalar dark
matter with quarks, gluons and photons via higher dimension operators that would arise from dimension-five
and dimension-six operators above electroweak scale, we perform a nonperturbative matching onto a heavy
baryon chiral perturbation theory that describes dark matter interactions with light mesons and nucleons.
This is then used to obtain the coefficients of the nuclear response functions using a chiral effective theory
description of nuclear forces. Our results consistently keep the leading contributions in chiral counting for
each of the initial Wilson coefficients. |
