耦合人工色模型中希格斯玻色子三线性自耦合的极限

Limit on Higgs boson trilinear self-coupling in coupled technicolor models

A. Doff, A. A. Natale

摘要:

三线性自耦合的希格斯玻色子,在一个理论中,这种玻色子是复合的,比较的实验约束的CMS实验获得的这个量。在一个模型的情况下,其中technicolor(TC)耦合到QCD,我们发现,实验结果已经约束的动力学的理论,这是由一个表达式的technicolor耦合模型的典型的technicolor自能($Σ_{tc}$),和功能的动态产生的technicolor质量和其他两个参数,描述technicolor动态质量动量依赖性。对这种动力学的限制使我们能够简单地确定这些理论中出现的伪戈德斯通玻色子的质量,这表明这些玻色子可能是相当大的。

英文摘要:

The trilinear self-coupling of the Higgs boson, in a theory in which this boson is composite, is compared to the experimental bound of this quantity obtained by the CMS experiment. In the case of a model where technicolor (TC) is coupled to QCD, we find that the experimental result already constrain the dynamics of the theory, which is represented by an expression of the technifermion self-energy ($Σ_{tc}$) typical of technicolor coupled models, and function of the dynamically generated technifermion mass and two other parameters that describe the technifermion dynamical mass momentum dependence. The limits imposed on this dynamics allow us to make a simple determination of pseudo-Goldstone boson masses that appear in these theories, indicating that these bosons may be expected to be quite massive.
