论文摘要
$^{12} $ c $(e,e'p)上的Quasi弹性散射在杰斐逊实验室的Chall C Hall C中进行了测量,用于太空样的4-Momentum Transfer squared $ q^2 $在8--14.2 \,(GEV/$ C $)的范围内(GEV/$ C $)$^2 $,proton Momenta含有最高proton Momenta,最高8.3 \,GEV,GEV,GEV,$ C $。该实验是在杰斐逊实验室升级的C厅C进行的。它使用现有的高动量光谱仪和新的超高动量光谱仪来检测散射的电子和质子的巧合。提取核透明度作为在平面波脉冲近似中计算得出的产率与计算的产量之比。此外,提取了$ 1S_ {1/2} $和$ 1P_ {3/2} $ 1p_ {3/2} $ shell Protons中的$^{12} $ C中的透明度,并检查了缺失动量分布的不对称性,以提示量子彩色动力学预测的量子彩色透明度的提示。所有这些结果都与传统的核物理学一致,并且与颜色透明度的发作不一致。
Quasi-elastic scattering on $^{12}$C$(e,e'p)$ was measured in Hall C at Jefferson Lab for space-like 4-momentum transfer squared $Q^2$ in the range of 8--14.2\,(GeV/$c$)$^2$ with proton momenta up to 8.3\,GeV/$c$. The experiment was carried out in the upgraded Hall C at Jefferson Lab. It used the existing high momentum spectrometer and the new super high momentum spectrometer to detect the scattered electrons and protons in coincidence. The nuclear transparency was extracted as the ratio of the measured yield to the yield calculated in the plane wave impulse approximation. Additionally, the transparency of the $1s_{1/2}$ and $1p_{3/2}$ shell protons in $^{12}$C was extracted, and the asymmetry of the missing momentum distribution was examined for hints of the quantum chromodynamics prediction of Color Transparency. All of these results were found to be consistent with traditional nuclear physics and inconsistent with the onset of Color Transparency.
