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