标题： Progress in the Understanding of Dijet Production in Deep-Inelastic Scattering

摘要： 最近来自HERA电子质子对撞机上的H1实验在深度非弹性散射中二喷注产生的最新结果被呈现。 在Breit系中，通过喷注形状和次喷注多重性研究了内部喷注结构。 这两个观测量都被QCD模型很好地描述。 我们观察到喷注在质子方向以及较低的横向喷注能量下出现扩展现象。 使用不同的喷注算法，在较宽的四动量转移范围（5 < Q^2 < 5000 GeV^2）和横向喷注能量范围（25 < E^2_t,Breit < 1200 GeV^2）内测量了二喷注率和二喷注截面。 强耦合常数的下一阶微扰QCD计算对数据给出了很好的描述。 显示英文摘要

摘要： Recent results on dijet production in deep-inelastic scattering from the H1 experiment at the ep-collider HERA are presented. Internal jet structure has been studied in terms of jet shapes and subjet multiplicities in the Breit frame. Both observables are seen to be well described by QCD models. We observe a broadening of the jets towards the proton direction and at lower transverse jet energies. Dijet rates and dijet cross sections have been measured over a wide range of four momentum transfers (5 < Q^2 < 5000 GeV^2) and transverse jet energies (25 < E^2_t,Breit < 1200 GeV^2) with different jet algorithms. Perturbative QCD calculations in next-to-leading order in the strong coupling constant give a good description of the data.
