标题： Dynamics of the Cosmological Quark-Hadron Transition in a Matter Dominated Universe: Distribution and Evolution of Baryon Inhomogeneities

摘要： 我们研究了夸克 - 强子相变的动力学，该场景下宇宙处于物质主导阶段，并且由质量为1-10 TeV的衰变粒子产生大量熵，这被大量超弦启发模型所建议。 我们估计了成核率，并计算了在相变过程中生成的重子涨子之间的平均间距，随后跟踪它们的演化直至原初核合成开始。 显示英文摘要

摘要： We study the dynamics of the quark-hadron transition for a scenario in which the Universe is matter dominated and a large amount of entropy is generated by decaying particles of mass 1--10 TeV, as suggested by a large class of superstring--inspired models. We estimate the nucleation rate and compute the mean separation between baryon fluctuations generated during the transition following their evolution up to the onset of primordial nucleosyntheisis.
