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

该提案将为T博士提供一年的支持。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合作将进行光子弹性散射和质子和中子产生π介子的测量，这反过来将提供一些关键低能预测的测试，如Drell-Hearn-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.
