Title: Dark Matter at the LHC: EFTs and gauge invariance
Abstract: Effective field theory (EFT) formulations of dark matter interactions have proven to be a con- venient and popular way to quantify LHC bounds on dark matter. However, some of the non- renormalizable EFT operators considered do not respect the gauge symmetries of the Standard Model. We carefully discuss under what circumstances such operators can arise, and outline poten- tial issues in their interpretation and application
