The Spurion Massive EFT (SMEFT)
Julian L. Northey, Yael Shadmi, Yotam Soreq +1
We use the amplitude formulation of the SMEFT to introduce a spurion analysis of the SMEFT low-energy amplitudes in terms of the Higgs VEV. Each SMEFT contact-term is given as a su…

Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing
Jared M Goldberg, Hongkai Liu, Yael Shadmi
We derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders. We first list the relevant dime…

Flavor at FASER: Discovering Light Scalars Beyond Minimal Flavor Violation
Reuven Balkin, Noam Burger, Jonathan L. Feng +1
We study a simple class of flavored scalar models, in which the couplings of a new light scalar to standard-model fermions are controlled by the flavor symmetry responsible for fer…
