Definition of pions
In the standard understanding of the strong force interaction as defined by quantum chromodynamics, pions are loosely portrayed as Goldstone bosons of spontaneously broken chiral symmetry. That explains why the masses of the three kinds of pions are considerably less than that of the other mesons, such as the scalar or vector mesons. If their current quarks were massless particles, it could make the chiral symmetry exact and thus the Goldstone theorem wo… WebSynonyms of peon. 1. : any of various workers in India, Sri Lanka, or Malaysia: such as. a. : infantryman. b. : orderly. 2. : a member of the landless laboring class in Spanish America.
