WebMar 3, 2024 · In this paper we will study the strong coupling constant. The recommended theoretical value for the strong coupling constant is αs=Euler's number/Gelfond's … In a quantum field theory with a coupling g, if g is much less than 1, the theory is said to be weakly coupled. In this case, it is well described by an expansion in powers of g, called perturbation theory. If the coupling constant is of order one or larger, the theory is said to be strongly coupled. An example of the latter is the hadronic theory of strong interactions (which is why it is called strong in the first place). In such a case, non-perturbative methods need be used to investigate the theory. lymphatic streaking cellulitis
