- Top Yukawa coupling enhancement in the composite Higgs models
- Time: 3:30 pm
- Place: 5280 Chamberlin
- Speaker: Da Liu, Argonne National Laboratory
- Abstract: The LHC Run 1 data prefer larger top Yukawa coupling and smaller ggh coupling. In this talk I will discuss about the possibility of explaining this behaviour in the composite Higgs models. We have found that<br>
the difference of the top Yukawa coupling strength ct and the ggh coupling strength cg is strongly related with Higgs mass term, i.e. a positive value of ct - cg will usually lead to positive <br>
Higgs mass term. In other words, we need other contributions to the Higgs potential to trigger the EWSB in order to fit the data. We also propose one possible solution to this problem. - Host: Josh Berger
