Inclusive Dijet Production at HERA: Direct Photon Cross Sections in Next-To-Leading Order QCD
نویسندگان
چکیده
We have calculated inclusive two-jet cross sections in next-to-leading order QCD for direct photoproduction in low Q2 ep collisions at HERA. Infrared and collinear singularities in real and virtual contributions are cancelled with the phase space slicing method. Analytical formulas for the different contributions giving the dependence on the slicing parameter are presented. Various oneand two-jet distributions have been computed demonstrating the flexibility of the method. ∗Supported by Bundesministerium für Forschung und Technologie, Bonn, Germany under Contract 05 6HH93P(5) and EEC Program ”Human Capital and Mobility” through Network ”Physics at High Energy Colliders” under Contract CHRX-CT93-0357 (DG12 COMA)

Inclusive Jet Production with Virtual Photons in Next-to-Leading Order QCD
We present a next-to-leading order calculation for the virtual photoproduction of one and two jets in ep collisions. Soft and collinear singularities are extracted using the phase space slicing method. The collinear photon initial state singularity depends logarithmically on the mass of the virtual photon and is absorbed into the virtual photon structure function. An MS factorization scheme is ...

متن کاملOpen charm production at HERA
Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading order (NLO) calculations. The NLO predictions are significantly below the data in some parts of the measured kinematic range. Angular distributions of dijet events with charm show clear evidence for the existence of charm originating from...
متن کاملJet Cross-Sections and αS in DIS at HERA
Measurements of inclusive-jet and dijet cross-sections in high-Q deep-inelastic scattering are presented together with a short overview of extractions of the strong coupling parameter αS from jets. The data samples used were collected with the ZEUS detector at HERA-1 and HERA-2. The measured distributions are compared to QCD calculations in next-to-leading order which describe the data very wel...
