报告简介

　　Beyond Standard Model (BSM) model building seeks to use effective field theory (EFT) approach to uncover the set of principles which determine how Nature behaves at a shorter distance scales than the Standard Model (SM) and to address one or more puzzles in the SM. Therefore, it is essential to understand the constraints that guide their construction and their phenomenological consequences. In this talk, we review the importance of Naturalness as a guiding principle in BSM model building, and consider additional constraints such as anomaly cancellation, asymptotic freedom/safety, vacuum stability, and unification of fundamental couplings. We find that while these constraints limit the number of consistent models, the existing models are still in their infancy, highlighting the need for further exploration in BSM model building.
