论PAMELA最新结果在天体粒子物理中的特殊意义

On the Special Significance of the Latest PAMELA Results in Astroparticle Physics

Goutam Sau, S. Bhattacharyya

摘要:

PAMELA小组在2010年继续进行早期的测量,报告了在更高能量下的反质子通量和$\bar{P}/P$比率的数据。过去,我们曾非常详细地处理过PAMELA数据的这些具体方面,每次我们都借助次级反质子的多重产生模型,加上一些非标准的同类和其他一些绝对标准的假设和近似,相当成功地捕捉到了当代数据的趋势。在这项工作中,我们的目标是提出一个全面的和有效的描述所有可用的数据,反质子通量和$\bar{P}/P$比率的性质,在最高的能量迄今为止,PAMELA实验在2010年。所有这些的主要物理含义最终都会被强调出来。

英文摘要:

In continuation of their earlier measurements, the PAMELA group reported data on antiproton flux and $\bar{P}/P$ ratios in 2010 at much higher energies. In past we had dealt with these specific aspects of PAMELA data in great detail and each time we captured the contemporary data-trends quite successfully with the help of a multiple production model of secondary antiprotons with some non-standard ilk and with some other absolutely standard assumptions and approximations. In this work we aim at presenting a comprehensive and valid description of all the available data on antiproton flux and the nature of $\bar{P}/P$ ratios at the highest energies reported so far by the PAMELA experiment in 2010. The main physical implication of all this would, in the end, be highlighted.
