baryon number n. Abbr. B A quantum number equal to the difference between the number of baryons and the number of antibaryons in a system of subatomic particles. The baryon number remains the same throughout any reaction and is one-third of the quark number. American Heritage® Dictionary...
Baryons are characterized by abaryon number,B,of 1. Their antiparticles, calledantibaryons, have a baryon number of −1. An atom containing, for example, one proton and one neutron (each with a baryon number of 1) has a baryon number of 2. In addition to their differences in composi...
any of a class of elementary particles that have a mass greater than or equal to that of the proton, participate in strong interactions, and have a spin of . Baryons are either nucleons or hyperons. Thebaryon numberis the number of baryons in a system minus the number of antibaryons ...
(particles built fromquarksand thus experiencing the strong nuclear force). Baryons are heavy subatomic particles that are made up of three quarks. Both protons and neutrons, as well as other particles, are baryons. (The other class of hadronic particle is built from aquarkand an antiquark ...
The formalism for a new generation of unquenched quark models for baryons is presented. The effects of quark-antiquark pairs are taken into account in an explicit form via a microscopic, QCD-inspired, quark-antiquark creation mechanism. As an application, the quark-antiquark contribution to the...

Using a very simple nonrelativistic model, a satisfactory agreement with the data, regarding angular distributions of the baryons emitted, is obtained. Predictions are given for other heavy vector meson decays into baryon-antibaryon pairs.关键词:...
These purely baryonic decays require at least three final-state particles in order to fullfil the empirical law of baryon number conservation3. The “lowest-ground” process is {{\rm{\Lambda }}}_{b}^{0}\to p\bar{p}n, discussed in ref. 3. We here focus our attention on the final...
A baryon is a composite subatomic particle made up of three quarks (as distinct from mesons, which comprise one quark and one antiquark). Baryons and mesons belong to the hadron family, which are the quark-based particles. 例句与用法 1. All particles which are together with the neutrons an...
