我们报道了质子，atv和gev的电子在共振区域上方的非弹性散射的宇称违反不对称性的测量。结果ppm与理论计算一致，并有助于验证这些计算中使用的干涉结构函数的建模，这些模型也用于确定双玻色子交换箱图（）对违反宇称的弹性散射测量的贡献。在包络产生中观察到一个正的违反宇称的不对称性，以及散射电子的正束-正常单自旋不对称性和包络产生的负束-正常单自旋不对称性。
We report the measurement of the parity-violating asymmetry for the inelastic scattering of electrons from the proton, atandGeV, above the resonance region. The resultppm agrees with theoretical calculations, and helps to validate the modeling of theinterference structure functionsandused in those calculations, which are also used for determination of the two-boson exchangebox diagram () contribution to parity-violating elastic scattering measurements. A positive parity-violating asymmetry for inclusiveproduction was observed, as well as positive beam-normal single-spin asymmetry for scattered electrons and a negative beam-normal single-spin asymmetry for inclusiveproduction.
