TC2模型中通过LHC胶子融合产生Top-希格斯玻色子

Top-Higgs boson production via gluon fusion at LHC in the TC2 model

Qing-Peng Qiao, Xue-Qian Li, Xue-Lei Wang

摘要:

在我们的工作中:0903.2612中,我们计算了单个top-希格斯玻色子玻色子在原top-technicolor模型的改进版本TC 2模型中的产生率。在arXiv:hep-ph/9905347 v2中讨论了类似的过程。正如我们在引言部分所讨论的,TC 2模型弥补了旧版本的一些缺点和漏洞。TC 2模型中的top-Higgs是top-Higgs与ETC模型中的top-Higgs的混合,因此引入参数$ε$来表示这种混合。此外,我们在300到800 GeV的范围内改变了顶部希格斯粒子的质量范围,而在arXiv:hep-ph/9905347 v2中,质量范围为200到400 GeV。数值计算结果表明,在200 ~ 400 GeV的质量范围内,TC 2模型和toptecnicolor模型中单个top-Higgs粒子的产生率非常接近.这表明,从原来的toptechnicolor模型到新的TC 2版本的变化并没有太大的影响顶希格斯粒子的产生率,即使在两个模型中的两个顶希格斯粒子是不同的。超过400 GeV,即使是TC 2模型预测LHC的生产率也可以忽略不计。由于现象学上的变化确实不明显,因此没有太多新的报道。尽管这两个模型在某种程度上是不同的,但我们认为结果不值得发表。因此,我们决定撤稿。

英文摘要:

In our work: 0903.2612, we calculate the production rate of single top-Higgs boson in the TC2 model which is a modified version of the original top-technicolor model. The similar process was discussed in arXiv:hep-ph/9905347v2. The TC2 model, as we discussed in the introduction part remedies some shortcomings and loophole of the old version. The top-Higgs in the TC2 model is a mixture of the top-Higgs of the toptechnicolor model and that of the ETC model, thus a parameter $ε$ is introduced to denote the mixture. Moreover, we vary the mass range of the top-Higgs within 300 to 800 GeV while in arXiv:hep-ph/9905347v2, the mass range was taken as 200 to 400 GeV. In the work, our numerical results show that the production rate of single top-Higgs in the TC2 model is very close to that in the toptecnicolor model within the mass range of 200 to 400 GeV. This manifests that change from the original toptechnicolor model to the new TC2 version does not much affect the production rate of the top-Higgs even though the two top-Higgs in the two models are different. Beyond the 400 GeV, even the TC2 model predicts a negligible production rate at LHC. Since the phenomenological change is indeed not obvious, there is not much new to report. Even though the two models are somehow different, we believe that the result is not worth publishing. Therefore we decide to withdraw our manuscript.
