论文摘要
未来指南针计划的主要部分是通过深层虚拟康普顿散射（DVC）和深层虚拟介子生产（DVMP）来研究核子结构的研究。 Compass将用高强度的160 GEV和2.5 m长的液态氢靶标测量DVC和DVMP反应，并由新的TOF系统包围。具有高能量和相反电荷和极化的MUON光束的可用性将允许访问与主要的GPD $ H $相关的Compton形式，并研究$ X_ {B} $ - 纯DVCS横截面的$ t $ - 依赖性和研究核子断层扫描。将提出有关实现准确性和初步测量结果的预测。
A major part of the future COMPASS program is dedicated to the investigation of the nucleon structure through Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP). COMPASS will measure DVCS and DVMP reactions with a high intensity muon beam of 160 GeV and a 2.5 m-long liquid hydrogen target surrounded by a new TOF system. The availability of muon beams with high energy and opposite charge and polarization will allow to access the Compton form factor related to the dominant GPD $H$ and to study the $x_{B}$-dependence of the $t$-slope of the pure DVCS cross section and to study nucleon tomography. Projections on the achievable accuracies and preliminary results of pilot measurements will be presented.
