AI总结:

本文提出一种非本地洛伦兹不变量子场论,该理论违反CPT定理,却同时具备可重整化和单位性,为非本地理论提供了新范例,并探讨其在解释宇宙反物质不对称性中的潜力。

摘要:

人们普遍认为任何相对论性非本地量子场论要么面临可重整化问题或单位性问题。而任何本地相对论量子场论(QFT)都具有CPT对称性。本文展示了一种之前提出的非本地洛伦兹不变QFT,其违反CPT定理,却同时具有可重整化和单位性,是文献中首次提出的此类非本地理论。该理论也满足因果性要求。进一步将此类非本地QFT扩展到包含规范理论也是可能的。特别是,给标准模型加上CP破坏相位,使理论满足大多数必要条件,最终解释宇宙反物质不对称性。至于反物质数破坏的必要性,有希望的几种可能性,如GUT和电弱重子生成、重子生成或sphalerons。

英文摘要:

It is a common belief that any relativistic nonlocal quantum field theory encounters either the problem of renormalizability or unitarity or both of them. It is also known that any local relativistic quantum field theory (QFT) possesses the CPT symmetry. In this Letter we show that a previously proposed nonlocal Lorentz invariant QFT, which violates the CPT theorem, is both renormalizable and unitary, thus being a first presented example in the literature of such a nonlocal theory. The theory satisfies the requirement of causality as well. A further generalization of such a nonlocal QFT to include the gauge theories is also envisaged. In particular, dressing such a Standard Model with a CP violating phase, will make the theory satisfying most of the necessary criteria to finally explain the baryon asymmetry of the universe by a viable QFT. As for the necessity of baryon number violation, there are hopefully several possibilities such as by GUT and electroweak baryogenesis, leptogenesis or sphalerons.
