EFT Validity and Truncation Uncertainty from few Nuisance Parameters
Benoît Assi, Adam Martin, William Shepherd
An observable in an Effective Field Theory (EFT) is an expansion in a set of small parameters, no different than any other perturbation series. Truncating such a series expansion l…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Report of the Topical Group on Electroweak Precision Physics and Constraining New Physics for Snowmass 2021
Alberto Belloni, Ayres Freitas, Junping Tian +65
The precise measurement of physics observables and the test of their consistency within the standard model (SM) are an invaluable approach, complemented by direct searches for new…
SMEFT at the LHC and Beyond: A Snowmass White Paper
William Shepherd
I detail an optimistic future vision for the use of SMEFT at high-energy colliders, and describe the use of the studies which could result for interpretation of future models. I al…
Truncation, validity, uncertainties
Ilaria Brivio, Sally Dawson, Jorge de Blas +19
The truncation of the standard-model effective field theory, its validity and the associated uncertainties have been discussed in meetings of the LHC EFT WG. Proposals were made by…
Measuring the polarization of boosted, hadronic bosons with jet substructure observables
Songshaptak De, Vikram Rentala, William Shepherd
In this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted bosons. We introduce a new jet substruc…
