Precision SMEFT with geoSMEFT

Location: 4138 Physics Research Building

Abstract: In this talk I'll describe how and why to do calculations in the Standard Model Effective Field Theory (SMEFT) out to higher orders in 1/\Lambda, where \Lambda is the scale suppressing higher dimensional operators. The key tool to performing these calculations is a reorganization of the SMEFT known as the geometric SMEFT, or geoSMEFT. Using calculations to O(1/\Lambda^4), I'll show circumstances where it is safe to ignore higher order effects and highlight scenarios where higher order terms are crucial to correctly interpreting deviations from the Standard Model.
