Energy-energy correlators in deep inelastic scattering

Jets in Deep Inelastic Scattering and High Energy

Recent results on jet production in neutral current deep inelastic scattering and high energy photoproduction at the HERA electron-proton-collider are briefly reviewed. The results are compared to QCD expectations in NLO and αs determinations using these data are summarized.

On High - Energy Inelastic Electron - Proton Scattering

Ultrahigh-Energy-Resolution Inelastic X-Ray Scattering

Very-high-energy-resolution measurements using X-rays can be achieved by extreme backreflection (Bragg angle close to 90°) f rom perfect crystals. This technique allowed the development of the instrument INELAX for inelastic scattering experiments at the HARWI wiggler at DORIS, DESY Hamburg. Recently, a high energy resolution of 9 meV could be achieved, and the instrument proved to be an excell...

Deep Inelastic Scattering

Recent deep inelastic results from the H1 collaboration are presented. The topics covered include inclusive diffractive physics, the determination of αS using the event shapes, the study of the hadronic final state at low x with single particles and with jets, the structure function measurements in particular F p 2 at low Q and the high Q physics both in neutral and charged current.

Deep Inelastic Scattering, Diffraction

These lectures include an introduction to the partonic description of the proton, the photon and the ‘colour singlet’, as seen in inclusive and semi-inclusive DIS, in e+e− collisions, and in diffractive processes, respectively. Their formal treatment using structure, fragmentation, and fracture functions is outlined giving an insight into the perturbative QCD framework for these functions. Exam...
