论文摘要

纯粹的虚拟量子的搜索引起了过去的兴趣。我们考虑各种建议,并将它们与假粒子或“假粒子”的概念进行比较。特别是,由于处方$ \ pmiε$的共存,feynman-wheeler繁殖器构成了Feynman图内使用Cauchy主值,违反了可义能力,单位性和稳定性。我们将Feynman,Fakeon和Feynman-Wheeler处方与剪切图进行了对比。假货没有Feynman-wheeler繁殖器的问题,并且是纯粹的虚拟量子的正确概念。它使我们能够在基本水平上理解量子重力,并将其与标准模型平等地置于平等的基础上。产生的量子重力理论具有扰动性,达到了令人难以置信的高能量。

The search for purely virtual quanta has attracted interest in the past. We consider various proposals and compare them to the concept of fake particle, or "fakeon". In particular, the Feynman-Wheeler propagator, which amounts to using the Cauchy principal value inside Feynman diagrams, violates renormalizability, unitarity and stability, due to the coexistence of the prescriptions $\pm iε$. We contrast the Feynman, fakeon and Feynman-Wheeler prescriptions in ordinary as well as cut diagrams. The fakeon does not have the problems of the Feynman-Wheeler propagator and emerges as the correct concept of purely virtual quantum. It allows us to make sense of quantum gravity at the fundamental level, and places it on an equal footing with the standard model. The resulting theory of quantum gravity is perturbative up to an incredibly high energy.
