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
\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
\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.
