引力诱导的四费米子接触相互作用意味着引力中介W和Z型规范玻色子

Gravity-induced four-fermion contact interaction implies gravitational intermediate W and Z type gauge bosons

Jens Boos, Friedrich W. Hehl

摘要:

费米子与引力的耦合必然导致不可重整化的引力四费米子接触相互作用。在这篇文章中,我们认为,增加适当的动力学项平方的引力规范场强度(挠率和曲率)的爱因斯坦-Cartan拉格朗日引起新的,大量的传播引力自由度。这与费米的有效四费米子相互作用及其涌现的W和Z玻色子非常相似。

英文摘要:

Coupling fermions to gravity necessarily leads to a non-renormalizable, gravitational four-fermion contact interaction. In this essay, we argue that augmenting the Einstein-Cartan Lagrangian with suitable kinetic terms quadratic in the gravitational gauge field strengths (torsion and curvature) gives rise to new, massive propagating gravitational degrees of freedom. This is to be seen in close analogy to Fermi's effective four-fermion interaction and its emergent W and Z bosons.
