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…

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…
