A new method for measuring the bottom quark Yukawa coupling at the CERN Large Hadron Collider

We propose a new method for measuring the bottom quark Yukawa coupling at the LHC. Higgs boson production in purely electroweak WHjj events is calculated. The Standard Model signal rate including decays W -> l nu and H -> bb is 11 fb for M_H = 120 GeV. It is possible to suppress the principal background, tt + jets, to below the level of the signal. As the top quark Yukawa coupling does not appear in this process, it promises a reliable extraction of g_Hbb in the context of extensions to the Standard Model, especially the MSSM.
