本文提出了在深度非弹性散射中测量单强子产生的束流螺旋度不对称性的方法。由爱马仕实验收集了27.6 GeV电子和正电子从气态氢和氘靶散射的数据。的不对称性分别作为一个函数的Bjorken标度变量，强子的横动量，和分数的能量带电π介子和K介子以及质子和反质子。这些不对称性也同时作为上述三个运动变量的函数。
A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets were collected by the HERMES experiment. The asymmetries are presented separately as a function of the Bjorken scaling variable, the hadron transverse momentum, and the fractional energy for charged pions and kaons as well as for protons and anti-protons. These asymmetries are also presented as a function of the three aforementioned kinematic variables simultaneously.
