WebNov 18, 2024 · The strong coupling constant of Quantum Chromodynamics (QCD), \(\alpha _s\), is, together with the quark masses, the main free parameter of the QCD Lagrangian.It enters into every process that involves the strong interaction and is the fundamental parameter of the perturbative expansion used in calculating cross sections for processes … All quarks and gluons in QCD interact with each other through the strong force. The strength of interaction is parameterized by the strong coupling constant. This strength is modified by the gauge color charge of the particle, a group-theoretical property. The strong force acts between quarks. See more The strong interaction or strong force is a fundamental interaction that confines quarks into proton, neutron, and other hadron particles. The strong interaction also binds neutrons and protons to create atomic nuclei, where … See more The word strong is used since the strong interaction is the "strongest" of the four fundamental forces. At a distance of 10 m, its strength is around 100 times that of the electromagnetic force, … See more The so-called Grand Unified Theories (GUT) aim to describe the strong interaction and the electroweak interaction as aspects of a single force, … See more • Christman, J.R.

It was known that the nucleus was composed of protons and neutrons and that protons possessed positive electric charge, while neutrons were electrically neutral. By the … See more Contrary to the description above of distance independence, in the post-Big Bang universe it is not the case that every quark in the universe attracts every other quark.
