Title: Feynman Rules for the Standard Model Effective Field Theory in R_xi-gauges

Assuming that New Physics effects can be parametrized within the Standard Model Effective Field Theory (SMEFT), written in a complete basis of gauge invariant operators up to dimension 6, the talk will focus on: i) the main steps necessary to obtain a consistent transition to the spontaneously broken theory, ii) important aspects of the theory, including the BRST-invariance of the SMEFT action for linear R_xi-gauges, iii) the Feynman Rules of the theory, expressed in a mass basis characterized by SM-like propagators.
