Constraining light quark Yukawa couplings from WH charge asymmetry

The charge asymmetry of the W boson associated Higgs production via H → τ τ is analyzed for indirect constraining the light quark Yukawa couplings. The WH of full run 2 data (2016 – 2018) are split by charge categories of the W boson. The inclusive signal strength and invariant mass spectra modified...

description The charge asymmetry of the W boson associated Higgs production via H → τ τ is analyzed for indirect constraining the light quark Yukawa couplings. The WH of full run 2 data (2016 – 2018) are split by charge categories of the W boson. The inclusive signal strength and invariant mass spectra modified datacards are compared with those obtained from the original charge category for validation. The current best-fit value of the inclusive charge asymmetry A = σ(W +h)-σ(W −h)/σ(W +h)+σ(W −h) is 0.152(-0.388/+0.379) The upper limit of kappa_c obtained from projection based on center-of-mass energy of 13 TeV, and luminosity of 3 ab-1 is 96.8.
