The Hierarchy Problem and the Top Yukawa: An Alternative to Top Partner Solutions (PRETALK for students at 15:30 h) (PRETALK for students at 15:30 h)
In traditional models, such as SUSY and CHM, top partners are introduced to cancel the top loop contribution to the Higgs mass term. However, the lack of evidence for these top partners required increasing fine-tuning in these types of models. To get a natural EWSB model, an alternative is preferred. In this talk, I will present solutions in another direction. Instead of canceling the top loop, we try to cut it off. It implies that the top Yukawa coupling has its sizable strength only in the infra-red, but gets strongly suppressed at high scales due to new interaction and degree of freedom. I will discuss both the possible UV completions and the related phenomenology.
