Nonrelativistic Yang-Mills Theory for a Naturally Light Higgs Boson
Laure Berthier, Kevin T. Grosvenor, Ziqi Yan
We continue the study of the nonrelativistic short-distance completions of a naturally light Higgs, focusing on the interplay between the gauge symmetries and the polynomial shift…
Statistics of predictions with missing higher order corrections
Laure Berthier, Jeppe Trøst Nielsen
Effective operators have been used extensively to understand small deviations from the Standard Model in the search for new physics. So far there has been no general method to fit…
Incorporating doubly resonant data in a global fit of SMEFT parameters to lift flat directions
Laure Berthier, Mikkel Bjørn, Michael Trott
We calculate the double pole contribution to two to four fermion scattering through currents at tree level in the Standard Model Effective Field Theory (SMEFT). We assume…
Effective interpretations of a diphoton excess
Laure Berthier, James M. Cline, William Shepherd +1
We discuss some consistency tests that must be passed for a successful explanation of a diphoton excess at larger mass scales, generated by a scalar or pseudoscalar state, possibly…
Consistent constraints on the Standard Model Effective Field Theory
Laure Berthier, Michael Trott
We develop the global constraint picture in the (linear) effective field theory generalisation of the Standard Model, incorporating data from detectors that operated at PEP, PETRA,…
