标题： Azimuthal Asymmetry and Transverse Momentum in Deep Inelastic Muon Scattering

摘要： 方位角不对称性和深度非弹性缪子散射中前向产生的带电强子的横向动量已作为事件运动学和强子变量的函数进行研究。 初始$k_T$的被击中部分子以及交叉截面的 O($\alpha_s$) 修正预计会对强子的横向动量和方位角不对称性做出贡献。 数据表现出一些在包含理论部分子级方位角不对称性的蒙特卡罗模拟中未出现的依赖关系。 显示英文摘要

摘要： The azimuthal asymmetry and the transverse momentum of forward produced charged hadrons in deep inelastic muon scattering have been studied as a function of the event kinematics and of the hadron variables. Primordial $k_T$ of the struck parton and O($\alpha_s$) corrections to the cross-section are expected to contribute to the transverse momentum and the azimuthal asymmetry of hadrons. The data show some unexpected dependences not present in a Monte Carlo simulation which includes the theoretical parton-level azimuthal asymmetry.
