Quantum Net Dynamics (Physics)

将对量子场论的一种基本替代方案--量子网络动力学(QND)进行理论物理研究。所讨论的网络是一种离散的量子微观因果结构，假设为时空。QND是局域的，局域有限的，局域相对论的，并且有一个基本的结构，其时间维度应该设置高能物理的时间、能量和长度的尺度。QND允许量子凝聚接近米尼科夫斯基时空和狄拉克方程，比基本时间大几倍。我们将研究费曼图计算规则的QND模拟，着眼于无紫外线无穷大的实际高能粒子计算。量子场论基本上是基本粒子物理学中唯一已知的实际计算方法。由于量子场论确实有其不足之处，因此对替代方案的研究，如这里将要进行的研究，是有价值的。

Theoretical physics research on a fundamental alternative to quantum field theory called Quantum Net Dynamics (QND) will be carried out. The net in question is a discrete quantum microscopic causal structure hypothesized for spacetime. QND is local, locally finite, locally relativistic and has a fundamental construct with the dimensions of time supposed to set the scales of times, energies, and lengths of high-energy physics. QND permits a quantum condensation that approaches Minikowski spacetime and the Dirac equation for times large compared to the fundamental time. The QND analogue of Feynman diagram calculational rules will be studied with an eye to practical high-energy particle calculations free of ultraviolet infinities. Quantum field theory is essentially the only known approach to practical calculations in elementary particle physics. Since quantum field theory does have its shortcomings, studies of alternatives, such as the study to be undertaken here, are valuable.
