用希格斯玻色子玻色子耦合探测sphaleron性质

Higgs boson coupling as a probe of the sphaleron property

Shinya Kanemura, Masanori Tanaka

摘要:

Sphaleron是电弱规范理论的一个非微扰解,它对电弱重子生成的研究至关重要。闪锌矿的能量取决于电弱对称性破缺机制的细节。我们发现,在许多新的物理模型中,sphaleron能量与标准模型预测值的偏差与三重希格斯玻色子玻色子耦合的偏差成正比,且符号相反。这个有趣的关系将是有用的,以确定sphaleron的能量,通过测量这种耦合在未来的对撞机实验。

英文摘要:

Sphaleron is a non-perturbative solution of electroweak gauge theories, which is crucially important for the scenario of electroweak baryogenesis. The sphaleron energy depends on details of the mechanism for the electroweak symmetry breaking. We find that in many of new physics models the deviation of the sphaleron energy from the prediction in the standard model is proportional to that of the triple Higgs boson coupling with opposite signs. This interesting relation would be useful to determine the sphaleron energy by measuring this couplings at future collider experiments.
