Threshold corrections in SMEFT
Anke Biekötter, Livia E. G. Maskos, Benjamin D. Pecjak
Threshold corrections provide a universal link between experimentally measured broken-phase parameters and renormalised symmetric-phase parameters used in SM…
State-of-the-art cross sections for ttH: NNLO predictions matched with NNLL resummation and EW corrections
Roger Balsach, Alessandro Broggio, Simone Devoto +13
We present new, state-of-the-art predictions for the associated production of the SM Higgs boson with top quarks, computed in accordance with the recommendations of the LHC Higgs W…
Analytic results for electroweak precision observables at NLO in SMEFT
Anke Biekötter, Benjamin D. Pecjak
We present analytic results for electroweak precision observables (EWPO) at next-to-leading order (NLO) in dimension-six SMEFT, with no assumptions on the flavour structure of SMEF…
Lorentz violating backgrounds from quadratic, shift-symmetric, ultralight dark matter
Minyuan Jiang, Benjamin D. Pecjak, Gilad Perez +1
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 effe…
