Semi-Inclusive Hadron Production at HERA: the Effect of QCD Gluon Resummation
نویسندگان
چکیده
We present a formalism that improves the applicability of perturbative QCD in the current region of semi-inclusive deep inelastic scattering. The formalism is based on all-order resummation of large logarithms arising in the perturbative treatment of hadron multiplicities and energy flows in this region. It is shown that the current region of semi-inclusive DIS is similar to the region of small transverse momenta in vector boson production at hadron colliders. We use this resummation formalism to describe transverse energy flows and charged particle multiplicity measured at the electron-proton collider HERA. We find good agreement between our theoretical results and experimental data for the transverse energy flows.

متن کاملBottom quark production cross section at fixed - target pp experiments
The cross section for bottom quark production at fixed-target energies is calculated for a wide range of beam momenta. A detailed analysis is given for the HERA-B experiment. We consider both the order α 3 s cross section and the resummation of soft gluon corrections in all orders of QCD perturbation theory. The inclusive transverse momentum and rapidity distributions, including resummation, fo...

Using a recently proposed factorization hypothesis for semi-inclusive hard processes in QCD, one can study, in principle, the diiractive production of the Standard Model Higgs boson at LHC using only, as input, ep diiractive hard-processes data of the type recently collected and analyzed by the H1 and ZEUS collaborations at HERA. While waiting for a more precise and complete set of data, we com...
متن کاملA Bfkl Monte Carlo Approach to Jet Production at Hadron-hadron and Lepton-hadron Colliders
Fixed-order QCD perturbation theory fails in some asymptotic regimes where large logarithms multiply the coupling constant. In those regimes resummation of the perturbation series to all orders is necessary to describe many high-energy processes. The Balitsky-FadinKuraev-Lipatov (BFKL) equation 1 performs such a resummation for virtual and real soft gluon emissions in dijet production at large ...

Abstract We study QCD effects in single graviton production at the CERN Large Hadron Collider (LHC) in the Randall-Sundrum (RS) Model. We present in detail the complete next-to-leading order (NLO) QCD corrections to the inclusive total cross sections. The NLO QCD corrections enhance significantly the total cross sections and decrease efficiently the dependence of the total cross sections on the...
