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…
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…
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…
An EFT hunter's guide to two-to-two scattering: HEFT and SMEFT on-shell amplitudes
Hongkai Liu, Teng Ma, Yael Shadmi +1
We derive the contact terms contributing to the four-point amplitudes of the standard-model particles, keeping terms with up to quartic energy growth. Imposing just the unbroken lo…
Theoretical developments in the SMEFT at dimension-8 and beyond
Simone Alioli, Radja Boughezal, Weiguang Cao +24
In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8…
On-shell Higgsing for EFTs
Reuven Balkin, Gauthier Durieux, Teppei Kitahara +2
We study the on-shell version of the Higgs mechanism in effective theories (EFTs) containing particles of different spins, focusing on contact terms as a simple starting point. We…
