Lorentz violating backgrounds from quadratic, shift-symmetric, ultralight dark matter
Abstract We consider an effective theory for a shift-symmetric, quadratically-coupled, ultralight spin-0 field. The leading CP conserving interactions with Standard Model fields in the effective theory arise at dimension 8. We discuss the renormalization group evolution and positivity bounds on thes...
