Diffractive jet production in lepton-hadron collisions
We study jet final states in diffractive deep-inelastic scattering. We present the QCD factorization formula in terms of diffractive parton distributions and discuss its implementation in NLO Monte Carlo generators. We compute NLO predictions for the diffractive jet cross section. We use this calculational framework to discuss theoretical models of the long-distance behavior.
متن کاملJet and hadron production in photon - photon collisions ∗
∗Heisenberg-Fellow hadronic fluctuations (“resolved”). Direct and resolved interactions can be separated by measuring the fraction xγ of the photon’s momentum participating in the hard interaction for the two photons. In γγ interactions they are labelled xγ for the two photons. Ideally, the direct γγ events with two bare photons are expected to have xγ = 1 and x − γ = 1, whereas for double-reso...
متن کاملA new approach to multi-jet calculations in hadron collisions
The ALPHA algorithm to evaluate the exact, tree-level matrix elements is reviewed in the context of multiparton processes in QCD. The algorithm is suited for the authomatic calculation of tree-level scattering amplitudes and allows for straightforward inclusion of mass effects. It’s CPU cost grows like K (K constant, n number of external particles) as opposed to the factorial growth of Feynman ...
متن کاملResonant Slepton Production in Hadron–Hadron Collisions
We consider the resonant production of sleptons via 6Rp in hadron–hadron collisions followed by supersymmetric gauge decays of the sleptons. We look at decay modes which lead to the production of a like-sign dilepton pair. The dominant production mechanism giving this signature is the resonant production of a charged slepton followed by a decay to a charged lepton and a neutralino which then de...
متن کاملHadron Production in Hadron-Hadron and Lepton-Hadron Collisions
We review a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments, which is performed at nextto-leading order (NLO) in the parton model of quantum chromodynamics endowed with nonperturbative fragmentation functions (FFs). Comparisons of pp data from CERN SppS and the Fermilab Tevatron and γp data from DESY HERA with the corresponding NLO ...
