在HERA进行喷流和粒子的精密测量

Precision measurements with jets and particles at HERA

Katharina Müller

摘要:

给出了用H1和ZEUS实验在不同运动学区域测量的EP碰撞中的包含射流和多射流截面。测量被用来提取强耦合α_s作为尺度的函数,并在Z玻色子的质量。与pQCD计算相比,从提示光子生产的结果显示在光生和深非弹性散射。其他主题地址缩放的带电粒子的动量分布,带电粒子的横向动量的测量和HERA的电荷不对称的第一次测量。

英文摘要:

Inclusive jet and multijet cross sections measured in ep collisions in different kinematic regions by the H1 and ZEUS experiments are shown. The measurements are used to extract the strong coupling alpha_s as a function of the scale and at the mass of the Z-boson. Results from prompt photon production in comparison with pQCD calculations are shown in photoproduction and deep-inelastic scattering. Other topics address scaled momentum distributions of charged particles, a measurement of the transverse momenta of charged particles and the first measurement of the charge asymmetry at HERA.
