SUMMARY:Phenomenology of Enhanced Light Quark Yukawa Couplings and the
Wh Charge Asymmetry\, Theory Seminar (High Energy/Cosmology)\, Felix
Yu
DESCRIPTION:I propose the measurement of the Wh charge asymmetry as a<
br>
\nconsistency test for the Standard Model Higgs\, which is sen
sitive
\nto enhanced Yukawa couplings of the first and second
generation
\nquarks. I present a collider analysis for the ch
arge asymmetry in the
\nsame-sign lepton final state\, pp to W
h to l nu l nu jj\,
\naimed at discovery significance for the
SM Wh
\nproduction mode in each charge channel with 300 fb^-
1 of 14 TeV
\nLHC data. Using this decay mode\, I estimate th
e statistical precision
\non the charge asymmetry should reach
0.4% with 3 ab^-1
\nluminosity\, enabling a strong consistenc
y test of the SM Higgs
\nhypothesis. I also discuss direct an
d indirect constraints on light
\nquark Yukawa couplings from
direct and indirect probes of the Higgs
\nwidth as well as Tev
atron and Large Hadron Collider Higgs data. While
\nthe main
effect from enhanced light quark Yukawa couplings is a rapid
\
nincrease in the total Higgs width\, such effects could be mitigated i
n
\na global fit to Higgs couplings\, leaving the Wh charge
\nasymmetry as a novel signature to test directly the Higgs coup
lings to
\nlight quarks.
