quark number

n.
A quantum number of subatomic particles or systems of such particles that equals the difference between the number of quarks and the number of antiquarks. This number is conserved in all interactions.

However, lattice QCD provide a technology to calculate the quark number susceptibilities with high accuracy [14].
In this paper we have calculated the evolution of chemical composition of the quark-gluon system with 2 + 1 staggered quark flavors, using diagonal quark number susceptibilities and the EOS calculated by Wuppertal-Budapest group.
Once the evolution the quark-gluon system is available, we can derive the evolution of the rapidity densities of quark numbers, [n.sub.i]([tau]) = 2[pi] [integral] rdr [[??].sub.i](r, [tau])/[[pi] [r.sup.2.sub.0]d[eta]].
Several recent findings have suggested particles with greater quark numbers (SN: 12/13/03, p.
