Holst action与动力学电弱对称破缺
Holst action and Dynamical Electroweak symmetry breaking
摘要：
我们考虑庞加莱引力以非极小的方式耦合到旋量。引力作用被认为是同时包含Palatini和Holst条款。由于挠率的存在，四个费米子之间的有效相互作用出现了，这可能导致费米子的左右不对称和凝聚。当进入引力作用量项的质量参数为Tev量级时，给出的结构可以提供动力学电弱对称破缺。这是通过将所有标准模型费米子安排在左手狄拉克旋量中而右手旋量保留给技术费米子来实现的。由于引力作用，技术费米子被凝聚，因此导致规范玻色子质量的出现。
英文摘要：
We consider Poincare gravity coupled in a nonminimal way to spinors. The gravitational action is considered that contains both Palatini and Holst terms. Due to torsion the effective four - fermion interactions appear that may lead to the left - right asymmetry and the condensation of fermions. When the mass parameter entering the mentioned terms of the gravitational action is at a Tev scale the given construction may provide the dynamical Electroweak symmetry breaking. This is achieved via an arrangement of all Standard Model fermions in the left - handed Dirac spinors while the right - handed spinors are reserved for the technifermions. Due to the gravitational action the technifermions are condensed and, therefore, cause the appearance of gauge boson masses.
