在双轻子W玻色子衰变中发现大于2 m_W的希格斯玻色子

Finding Higgs bosons heavier than 2 m_W in dileptonic W-boson decays

Alan J. Barr, Ben Gripaios, Christopher G. Lester

摘要:

我们重新考虑了通过双轻子衰变h -> WW -> l nu l nu发现重希格斯玻色子(m_h > 2m_W)的观测值。我们发现,观测量概括的横向质量,考虑到这两个中间W玻色子很可能是壳上的一个显着的改善,在现有的搜索中使用的变量。我们还评论这些可观的应用程序进行通过窄宽度中间体的其他衰变。

英文摘要:

We reconsider observables for discovering a heavy Higgs boson (with m_h > 2m_W) via its di-leptonic decays h -> WW -> l nu l nu. We show that observables generalizing the transverse mass that take into account the fact that both of the intermediate W bosons are likely to be on-shell give a significant improvement over the variables used in existing searches. We also comment on the application of these observables to other decays which proceed via narrow-width intermediates.
