用低质量μ子对发现希格斯玻色子

Discovering the Higgs with Low Mass Muon Pairs

Mariangela Lisanti, Jay G. Wacker

摘要:

许多电弱对称性破缺模型都有一个额外的轻赝标。如果希格斯玻色子可以衰变为一个新的赝标量,LEP对希格斯玻色子的搜索就可以大大改变,希格斯玻色子可以轻到86 GeV。在这些模型中发现希格斯玻色子是具有挑战性的,当赝标量小于10 GeV时,因为它主要衰变为τ轻子。在本文中,我们讨论发现希格斯粒子的次显性衰变模式,其中一个伪标量衰变为一对μ子。这种搜索允许潜在的发现级联衰减的希格斯玻色子与完整的Tevatron数据集或早期数据在大型强子对撞机。

英文摘要:

Many models of electroweak symmetry breaking have an additional light pseudoscalar. If the Higgs boson can decay to a new pseudoscalar, LEP searches for the Higgs can be significantly altered and the Higgs can be as light as 86 GeV. Discovering the Higgs boson in these models is challenging when the pseudoscalar is lighter than 10 GeV because it decays dominantly into tau leptons. In this paper, we discuss discovering the Higgs in a subdominant decay mode where one of the pseudoscalars decays to a pair of muons. This search allows for potential discovery of a cascade-decaying Higgs boson with the complete Tevatron data set or early data at the LHC.
