天体物理奇异粒子产生的多重碎裂模型
Multifragmentation model for the production of astrophysical strangelets
摘要：
本文试图用统计反汇编模型来确定银河系中致密双星系统中奇异星合并过程中喷出的奇异夸克物质的重子数（或质量）分布。分析中考虑了奇异夸克的有限质量。由此产生的电荷的奇异和相应的库仑修正包括得到一个合理的大小分布的奇异，因为它们产生的双星合并，从而得到注入银河系。根据奇异星在其源处的质量分布，利用一个简单的银河系中奇异星传播的扩散模型，试图对奇异星在太阳附近的可能通量进行一个近似的数量级估计。鉴于目前正在努力通过最近的卫星实验探测银河系奇异星，这种理论估计是重要的。
英文摘要：
Determination of baryon number (or mass) distribution of the strangelets, that may fragment out of the warm and excited strange quark matter ejected in the merger of strange stars in compact binary stellar systems in the Galaxy, is attempted here by using a statistical disassembly model. Finite mass of strange quarks is taken into account in the analysis. Resulting charges of the strangelets and the corresponding Coulomb corrections are included to get a plausible size distribution of those strangelets as they are produced in binary stellar mergers thus getting injected in the Galaxy. From this mass distribution of strangelets at their source, an approximate order of magnitude estimate for their possible flux in solar neighborhood is attempted by using a simple diffusion model for their propagation in the Galaxy. Such theoretical estimate is important in view of the ongoing efforts to detect galactic strangelets by recent satellite-borne experiments.
