SUMMARY:Top Yukawa coupling enhancement in the composite Higgs models\
 , Theory Seminar (High Energy/Cosmology)\, Da Liu\, Argonne National L
 aboratory
DESCRIPTION:The LHC Run 1 data prefer larger top Yukawa coupling and s
 maller 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><br>
\nthe difference of the top Yukawa coupling strengt
 h 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 posi
 tive <br><br>
\nHiggs mass term. In other words\, we need other contri
 butions to the Higgs potential to trigger the EWSB in order to fit the
  data. We also propose one possible solution to this problem.
