摘要：

A model of the q-q interaction which avoids complete confinement is employed to calculate the number of free quarks which survive from the early universe. For a free-quark mass M10 GeV, our results are similar to those of previous calculations. But for M10 GeV, the number per nucleon is given by ln(qN)=ln(qN)=-MkT*+2ln(MkT*)+C, where the constant C20. Quarks of such mass freeze out of equilibrium during the quark-hadron transition at a temperature 0.2T*0.4 GeV/k, which for instance predicts 15M30 GeV if (q+q)N10-20. © 1979 The American Physical Society.
