标题： Baryon Isocurvature Perturbation in the Affleck-Dine Baryogenesis mechanism

摘要： 我们提出了一个原始重子等曲率模型，该模型基于 Affleck-Dine（AD）重子生成机制。 在暴胀期间，AD场的量子涨落会产生重子数的涨落。 我们得到了一个模型，它既提供了适当的比例重子数与熵比值$10^{-11}$，又在谱的转折点 1 Mpc 处提供了高斯重子等曲率扰动$10^{-3}$，并且在大于 1 Mpc 的大尺度上具有陡峭的谱$n=-1.5$。 显示英文摘要

摘要： We propose a primeval baryon isocurvature model in the context of the Affleck-Dine (AD) baryogenesis mechanism. Quantum fluctuations of the AD field during inflation produce fluctuations in the baryon number. We obtain a model which gives both the appropriate baryon to entropy ratio of the order $10^{-11}$ and the gaussian baryon isocurvature perturbation of the order $10^{-3}$ at the break of the spectrum 1 Mpc with the steep spectrum $n=-1.5$ on large scales >1 Mpc.
