چکیده

We present the perturbative prediction for three-jet production cross section in deep inelastic scattering at the next-to-leading order accuracy. We study the dependence on the renormalization and factorization scales of exclusive three-jet cross section. The perturbative prediction for the three-jet differential distribution as a function of the momentum transfer is compared to the corresponding data obtained by the H1 Collaboration at HERA.

Dijet production in neutral current deep inelastic scattering at HERA

Dijet cross sections in neutral current deep inelastic ep scattering have been measured in the range 10 < Q < 10 GeV with the ZEUS detector at HERA using an integrated luminosity of 38.4 pb. The cross sections, measured in the Breit frame using the kT jet algorithm, are compared with next-to-leading-order perturbative QCD calculations using proton parton distribution functions. The uncertaintie...

NLO QCD calculations in DIS at HERA based on the dipole formalism∗

We briefly describe a new general algorithm for carrying out QCD calculations to next-to-leading order in perturbation theory. The algorithm can be used for computing arbitrary jet cross sections in arbitrary processes and can be straightforwardly implemented in general-purpose Monte Carlo programs. We show numerical results for the specific case of jet cross sections in deep inelastic scatteri...

Inclusive Single Hadron Production in Neutral Current Deep-Inelastic Scattering at Next-to-Leading Order

A study of inclusive production of single hadrons with finite transverse momentum in neutral current deep-inelastic scattering has been carried out. Cross sections have been calculated using perturbative Quantum Chromodynamics at next-to-leading order and compared to HERA data. Predictions for light charged hadron production data were also calculated for large values of Q to show the possible e...
