格点规范理论与质量的起源
Lattice Gauge Theory and the Origin of Mass
摘要:
日常生活中物体的大部分质量存在于原子核中;电子的总质量加起来不到千分之一。原子核是由核子--质子和中子--组成的,它们的核结合能虽然在人的尺度上是巨大的,但与它们的静止能量相比是很小的。核子则是无质量胶子和近无质量夸克的复合体。正是这些受限物体的能量,通过$M=E/c^2$,造成了每天的质量。本文讨论了这种机制的物理和作用的格点规范理论在建立其连接到量子色动力学。
英文摘要:
Most of the mass of everyday objects resides in atomic nuclei; the total of the electrons' mass adds up to less than one part in a thousand. The nuclei are composed of nucleons---protons and neutrons---whose nuclear binding energy, though tremendous on a human scale, is small compared to their rest energy. The nucleons are, in turn, composites of massless gluons and nearly massless quarks. It is the energy of these confined objects, via $M=E/c^2$, that is responsible for everyday mass. This article discusses the physics of this mechanism and the role of lattice gauge theory in establishing its connection to quantum chromodynamics.
