Double Polarization Measurements with Real Photons and Measurement of Direct CP Violation

这项提案将为T.Kageya博士提供为期一年的支持，他是布鲁克海文国家实验室激光电子伽马源(LEGS)的博士后研究员。LEGS的合作将对质子和中子的光子弹性散射和pi介子的产生进行测量，这将反过来测试一些关键的低能量预测，如Drell-Hain-Gerasimov求和规则，以及手征微扰理论。

This proposal will provide support for one year for Dr. T. Kageya, a postdoctoral fellow working at the Laser Electron Gamma Source (LEGS) at Brookhaven National Laboratory. The LEGS collaboration will carry out measurements of photon elastic scattering and pi meson production from protons and neutrons, which will in turn provide tests of some key low-energy predictions, such as the Drell-Hearn-Gerasimov sum rule, as well as chiral perturbation theory.
