SUMMARY:Seminar: 'NLO Running in the SMEFT'
DESCRIPTION:Title: ‘NLO Running in the SMEFT’ \nSpeaker: Lukas Born (University of Bern). \nVenue&Time: Red Room / 15:00 \nAbstract: The Standard Model Effective Field Theory (SMEFT) provides a systematic framework for parameterizing heavy new physics in a model-independent way. A central ingredient for precision analyses within this framework is the renormalization group equations (RGEs)\, governing the running of the Wilson coefficients across energy scales. Our recent computation of the two-loop β-functions in the SMEFT marks a milestone in this program\, opening the door to genuine next-to-leading order (NLO) analyses. \nIn this talk\, I will first discuss the key technical challenges we encountered in our calculation\, how we addressed them by modifying the Warsaw basis\, and the consistency checks on our results. Second\, I will turn to a concrete phenomenological application\, demonstrating that NLO running effects play an important role in Electroweak Precision Observables (EWPO).
