广义Horava引力的幂计数重整化

Power-counting renormalizability of generalized Horava gravity

Matt Visser

摘要:

在之前的一篇文章[arXiv:0902.0590 [hep-th],Phys. Rev D80(2009)025011]中,我讨论了在量子场论中允许洛伦兹对称破缺的潜在好处。特别地,我讨论了正规序:P(phi)^{z>=d}_{d+1}:标量量子场论的微扰幂次计数有限性,并概述了Horava的量子引力模型的含义。在当前相当简短的附录中,我将整理一些悬而未决的问题,并填写一些论证的技术细节,这些论证表明在(d+1)维中Horava引力的z>=d变体的幂计数重正化性。

英文摘要:

In an earlier article [arXiv:0902.0590 [hep-th], Phys. Rev D80 (2009) 025011], I discussed the potential benefits of allowing Lorentz symmetry breaking in quantum field theories. In particular I discussed the perturbative power-counting finiteness of the normal-ordered :P(phi)^{z>=d}_{d+1}: scalar quantum field theories, and sketched the implications for Horava's model of quantum gravity. In the current rather brief addendum, I will tidy up some dangling issues and fill out some of the technical details of the argument indicating the power-counting renormalizability of a z>=d variant of Horava gravity in (d+1) dimensions.
