baryon number

[′bar·ē‚än ‚nəm·bər]
(particle physics)
A quantum number equal to the number of baryons minus the number of antibaryons in a system; it is conserved at the present level of detection, but may not be exactly conserved.

Therefore, one may ask, in spite of significantly correlated production due to baryon number, electric charge conservation, and kinematical correlations of proton and antiprotons, why do the measured cumulants follow the independent production model.

[??] is the H- baryon number. [Q.sub.em] is the electric charge.
In 1976't Hooft discovered that baryon number is violated in the Standard Model and it is due to transition between two topologically distinct SU[(2).sub.L] ground states [76, 77].
As a result, globally conserved quantum numbers (charge, strangeness, and baryon number) must be conserved locally in spatially restricted correlation clusters.

In case of three flavor quarks, these are strangeness, baryon number, and electric charge or, equivalently, the three quark flavors: up, down, and strange.
