探索希格斯扇区光谱学
Exploring Higgs Sector Spectroscopy
摘要:
标准模型的希格斯扇区是场理论上一个非常有趣的理论。由于强耦合域和弱耦合域是连续相连的,只有数量的变化才能区分不同的区域。特别是,这是真正的渐近谱,它只能由规范不变的复合,即。e.邦,邦。由于在某些区域的参数空间甚至Regge轨迹预计存在,有立即的可能性,共振也可能存在于参数区域的特性的标准模型希格斯部门。这种可能性进行了详细讨论,从定义的理论光谱,包括激发态分析,一些考虑这是否可能有实验结果。这种探索的最大限制是没有费米子的规范耦合运行得更快,因此规范扇区可能会受到影响。
英文摘要:
The Higgs sector of the standard model is field-theoretically a very interesting theory. Because strong and weak coupling domains are continuously connected, only quantitative changes distinguish the various regions. Especially, this is true for the asymptotic spectrum, which can only consist out of gauge-invariant composite, i. e. bound, states. Since in some regions of parameter space even Regge trajectories are expected to exist, there is immediately the possibility that resonances may also be present in the parameter region characteristic of the standard model Higgs sector. This possibility is discussed in some detail, starting from the definition of the theory to spectroscopy, including excited state analysis, to some considerations whether this could have experimental consequences. The strongest limitation for this exploration turns out to be that the gauge coupling without fermions runs much faster, and the gauge sector is therefore potentially affected.
