论文摘要
我们研究早期宇宙中的底味丰度,接近温度$ t_ \ mathrm {h} \ simeq150 \,\ mathrm {Mev} $,这是对夸克夸克 - 格鲁恩plasma(QGP)的夸张夸克 - 格鲁恩plasma(QGP)的状态。我们显示底部风味丰度持续的微秒。在我们的研究中,我们在QGP中都使用它,以及在$ t_ \ mathrm {h} $附近的HADRONIC GAS阶段(HG)$ b $和$ \ bar b $ Quarks均受B-Mesons和Antimes的约束,遭受违反弱衰减的$ CP $。底部风味的一致性非平衡丰度可以以必需的强度导致物质发生: b)考虑时间尺度,数百万个B-Meson衰减周期以及$ b \ bar b $ -PAIR娱乐过程。
We study bottom flavor abundance in the early Universe near to a temperature $T_\mathrm{H}\simeq150\,\mathrm{MeV}$, the condition for hadronization of deconfined quark-gluon plasma (QGP). We show bottom flavor abundance nonequilibrium lasting microseconds. In our study we use that in both QGP, and the hadronic gas phase (HG) $b$ and $\bar b$ quarks near $T_\mathrm{H}$ are bound in B-mesons and antimesons subject to $CP$ violating weak decays. A coincident non-equilibrium abundance of bottom flavor can lead to matter genesis at required strength: a) The specific thermal yield per entropy is $n_b^{th}/σ=10^{-10}\sim10^{-13}$. b) Considering time scales, millions of cycles of B-meson decays, and $b\bar b$-pair recreation processes occur.
