在HERA用ZEUS探测器进行包合衍射:选择方法的比较

Inclusive diffraction with the ZEUS detector at HERA: a comparison among selection methods

Marta Ruspa

摘要:

利用HERA的ZEUS探测器,通过分析强子末态的质量分布M_X,以及直接标记质子,研究了γ *p -> Xp虚光子的衍射解离。在质子动量损失较低的情况下,考虑质子解离事件的不同处理和贡献,三种方法得到的衍射结构函数测量结果是一致的。

英文摘要:

The diffractive dissociation of virtual photons, gamma*p -> Xp, has been studied with the ZEUS detector at HERA by requiring a large rapidity gap between X and the outgoing proton, by analysing the mass distribution, M_X, of the hadronic final state, as well as by directly tagging the proton. At low values of the proton momentum loss, the diffractive structure function measurements obtained with the three methods are consistent, provided the different treatment and contributions of proton-dissociative events are taken into account.
