复合希格斯粒子到双光子和胶子

Composite Higgs to two Photons and Gluons

Tuomas Hapola, Francesco Sannino

摘要:

本文介绍了一个简单的框架来估计复合希格斯玻色子与双光子的耦合,在标准模型的Technicolor扩展。同样的框架使我们能够预测复合希格斯到双胶子的过程。我们比较的衰减率与标准模型的,并表明,通常的一阶修正。因此,我们认为,双光子衰变过程可以有效地用来解开一个轻的复合希格斯从标准模型之一。我们还表明,Tevatron的胶子-胶子融合生产的希格斯要么排除techniquark携带色荷到95%的置信水平,如果复合希格斯是轻的,或者后者必须重于200 GeV左右。

英文摘要:

We introduce a simple framework to estimate the composite Higgs boson coupling to two-photon in Technicolor extensions of the standard model. The same framework allows us to predict the composite Higgs to two-gluon process. We compare the decay rates with the standard model ones and show that the corrections are typically of order one. We suggest, therefore, that the two-photon decay process can be efficiently used to disentangle a light composite Higgs from the standard model one. We also show that the Tevatron results for the gluon-gluon fusion production of the Higgs either exclude the techniquarks to carry color charges to the 95% confidence level, if the composite Higgs is light, or that the latter must be heavier than around 200 GeV.
