Abstract: The Standard Model Effective Field Theory (SMEFT) is one of the most promising tools for precision based discoveries at the LHC. Calculation in the SMEFT are often fraught with inconsistencies in the power counting expansion. The recent geometric reformulation of the SMEFT (geoSMEFT)allows us to perform calculations at NLO in the SMEFT expansion, and in many cases all orders in the SMEFT expansion. In this talk I will introduce the basic idea behind effective field theories, discuss the SMEFT and its use for LHC phenomenology, and demonstrate how the geoSMEFT is formulated. I'll then demonstrate some of the recent applications of the geoSMEFT and discuss how it may help elucidate the theory error associated with the truncation of the SMEFT expansion.
