2-GeV/c $\leq P_{lab}\leq$ 16-GeV/c间$\bar PP$弹性散射微分截面的参数化
Parametrization of the $\bar PP$ Elastic Scattering Differential Cross Section Between 2 GeV/c $\leq P_{lab}\leq$ 16 GeV/c
摘要:
本文提出了一种在束流动量为2 ~ 16 GeV/c范围内的$\bar pp$微分弹性散射截面的参数化方法。参数化很好地描述了现有的数据,包括在四动量转移$|t|$高达1.5-2.0 GeV的$^2$观察到的衍射图案。它可用于详细计算为未来达姆施塔特FAIR设施的PANDA探测器设计的探测器上的辐射负荷。
英文摘要:
A parameterization of the $\bar pp$ differential elastic scattering cross section in the beam momentum range from 2 to 16 GeV/c is proposed. The parameterization well describes the existing data including the observed diffraction pattern at four-momentum transfer $|t|$ up to 1.5-2.0 GeV$^2$. It can be used for detailed calculations of the radiation load on the detectors being designed for the PANDA detector at the future FAIR facility in Darmstadt.
