The number of quarks of each type, u, d, s, etc., is conserved in strong interaction processes. Flavor is a good quantum number only in the limit that weak force can be ignored. As it stands, it is more convenient to examine the baryon number, which is known to be conserved under ...

The replacement of a d quark in the nucleon by an s quark produces a baryon state with spin parity + and strangeness number s = -1, the latter being given by [n(s) - n(s)], where n(q) denotes the number of quarks of type q in the system considered. The states thus reached ...
is an American physicist born in 1932, who is Professor of physics at the University of Maryland at College Park) introduced a three-valued charge degree of freedom to quarks (Greenberg, 1964), which means that this new charge quantum number would be different for each of the three quarks....

The obvious exceptions are the d = 9 operators involving three quarks, one lepton, and two anti-leptons, already discussed in ref. [27] because of their potentially unique lepton-flavor properties. As an example, consider the operator dddℓℓ¯ℓ¯/Λ5; antisymmetry enforces once of...
With the two quarks moving towards the quark end and two anti-quarks moving towards the anti-quark end. We created two string pieces, each carrying a non-zero baryon number. For the qq¯-fluctuation to live long enough for the string to break in between, the momenta of the q must be...
