Properties ofe^ + e^ - \to h\bar h in the\Upsilon (b\bar b)-continuum

The unflavored hadrons frome ⁺ e ^? annihilation in the \(\Upsilon (b\bar b)\) -continuum are analyzed in terms of the covariant Boltzmann distribution with an equilibrium temperature 151 MeV according to the Stefan's law. It is found that the effective fugacities of quark contents are approximately equal to the reciprocals of those from othere ⁺ e ^? annihilations outside the γ-continuum, whereas the fireballs are practically stationary, reflecting the decay at rest of \(B\bar B\) mesons produced by thee ⁺ e ^? annihilation.
