在HERA上对QCD包含衍射分析的新进展

New developments in QCD analysis of inclusive diffraction at HERA

Laurent Schoeffel

摘要:

HERA的H1和ZEUS探测器已经获得了大量关于虚光子衍射解离的结果,$γ^{\star}p \to Xp$。不同的实验技术已被使用,通过要求一个大的快度间隙之间的$X$和出射质子,通过分析的质量分布,$M_X$,强子的最终状态,以及通过直接标记的质子。已经观察到这些技术之间以及H1和ZEUS结果之间的合理兼容性。测量中的一些共同的基本特征也存在于所有数据集中。衍射PDF可以很好地说明这些功能。在这些会议记录中讨论了各种想法和新的发展。

英文摘要:

A large collection of results for the diffractive dissociation of virtual photons, $γ^{\star}p \to Xp$, have been obtained with the H1 and ZEUS detectors at HERA. Different experimental techniques have been used, 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. A reasonable compatibility between those techniques and between H1 and ZEUS results have been observed. Some common fundamental features in the measurements are also present in all data sets. Diffractive PDFs can give a good account of those features. Ideas and new developments are discussed in these proceedings.
