Abstract :
We propose a new method for measuring the H→bb̄ rate at the CERN Large Hadron Collider in a manner which would allow extraction of the b quark Yukawa coupling. Higgs boson production in purely electroweak WHjj events is calculated. The Standard Model signal rate including decays W→ℓν and H→bb̄ is 11 fb for MH=120 GeV. It is possible to suppress the principal backgrounds, Wbb̄jj and tt̄jj, to approximately the level of the signal. As the top quark Yukawa coupling does not appear in this process, it promises a reliable extraction of gHbb in the context of the Standard Model or some extensions, such as the MSSM.
