Tevatron中希格斯玻色子的半轻子衰变

Semileptonic decays of the Higgs boson at the Tevatron

Joseph D. Lykken, Adam O. Martin, Jan-Christopher Winter

摘要:

我们研究了通过包括半轻子希格斯玻色子衰变h --> WW --> l nu jj(M_h >~ 2 M_W)和h --> W jj --> l nu jj(M_h <~ 2 M_W)来扩展标准模型希格斯玻色子的Tevatron范围的前景,其中j是强子喷注。我们采用了现实的模拟信号和背景使用夏尔巴蒙特卡罗事件发生器。我们发现运动学的选择,提高了占主导地位的W+喷气机背景的信号。由此产生的灵敏度可能是对正在进行的搜索的重要补充,特别是在质量范围120 <~ M_h <~ 150 GeV。所描述的技术可以扩展到大型强子对撞机上的希格斯玻色子搜索。

英文摘要:

We examine the prospects for extending the Tevatron reach for a Standard Model Higgs boson by including the semileptonic Higgs boson decays h --> WW --> l nu jj for M_h >~ 2 M_W, and h --> W jj --> l nu jj for M_h <~ 2 M_W, where j is a hadronic jet. We employ a realistic simulation of the signal and backgrounds using the Sherpa Monte Carlo event generator. We find kinematic selections that enhance the signal over the dominant W+jets background. The resulting sensitivity could be an important addition to ongoing searches, especially in the mass range 120 <~ M_h <~ 150 GeV. The techniques described can be extended to Higgs boson searches at the Large Hadron Collider.
