Weyl几何引力与电弱对称性的“破缺”

Weyl geometric gravity and "breaking" of electroweak symmetry

Erhard Scholz

摘要:

重新考虑了Omote、Dirac和Utiyama(1971 ff)关于引力的Weyl几何标度协变方法。考虑到基本粒子场的基本标度自由,它可以推广到基本粒子场的电弱部分。Cheng(1988)已经指出,通常归因于在$0.1 - 0.3 \,TeV$处有玻色子的希格斯场的电弱对称性破缺,可能是由于外尔几何引力和电弱相互作用之间的耦合。外尔几何似乎很适合于处理基本粒子物理学的问题,这些问题与标度不变性及其“破缺”有关。这种设置表明,在$\sim 1\, eV$的惊人低能量下存在标量场玻色子。这似乎不太可能;但是,作为回报,质量的获得是与引力耦合的结果,这与把质量理解为场的引力荷是一致的。

英文摘要:

A Weyl geometric scale covariant approach to gravity due to Omote, Dirac, and Utiyama (1971ff) is reconsidered. It can be extended to the electroweak sector of elementary particle fields, taking into account their basic scaling freedom. Already Cheng (1988) indicated that electroweak symmetry breaking, usually attributed to the Higgs field with a boson expected at $0.1 - 0.3 \,TeV$, may be due to a coupling between Weyl geometric gravity and electroweak interactions. Weyl geometry seems to be well suited for treating questions of elementary particle physics, which relate to scale invariance and its "breaking". This setting suggests the existence of a scalar field boson at the surprisingly low energy of $\sim 1\, eV$. That may appear unlikely; but, as a payoff, the acquirement of mass arises as a result of coupling to gravity in agreement with the understanding of mass as the gravitational charge of fields.
