CLAS12及其在杰斐逊实验室升级的初始科学计划

CLAS12 and its initial Science Program at the Jefferson Lab Upgrade

Volker D. Burkert

摘要:

CLAS12探测器的概述和杰斐逊实验室的电子加速器的能量加倍后的初始物理程序。12 GeV升级项目的建设已于2008年10月开始。一个广泛的程序已经开发,通过测量深刻的排他性和半包容性的过程映射核子的三维自旋和风味的内容。其他的程序包括大$x_{B} \le 0.85$的前向分布函数和夸克和胶子极化分布函数,以及高$Q^2$的核子基态和跃迁形状因子。12 GeV的电子束和CLAS12的大接受度也非常适合于利用核作为实验室来探索强子化性质

英文摘要:

An overview of the CLAS12 detector is presented and the initial physics program after the energy-doubling of the Jefferson Lab electron accelerator. Construction of the 12 GeV upgrade project has started October 2008. A broad program has been developed to map the nucleon's 3-dimensional spin and flavor content through the measurement of deeply exclusive and semi-inclusive processes. Other programs include forward distribution function to large $x_{B} \le 0.85$ and of the quark and gluon polarized distribution functions, as well as nucleon ground state and transition form factors at high $Q^2$. The 12 GeV electron beam and the large acceptance of CLAS12 are also well suited to explore hadronization properties using the nucleus as a laboratory
