A puzzling aspect of standard factorized QCD predictions1 for massive lepton-pair production in hadronic collisions is the absence of any corrections to the cross section due to the effects of initial state

چکیده
We show that initial state interactions violate the usual QCD factorization predictions for massive lepton-pair production in leading twist. The initial state collisions correct do/dQ2dxF and also smear the lepton-pair transverse momentum distribution.

QCD Factorization and Re-scattering in Proton-Nucleus Collisions
The extension of the factorization theorems of perturbative QCD to power corrections associated with re-scattering in nuclear collisions is reviewed. The importance of hadron-nucleus collisions is discussed. Perturbative QCD (pQCD) has been very successful in interpreting and predicting hadronic scattering processes in high energy collisions, even though the physics associated with individual h...
متن کاملQCD corrections to hadronic WWZ production with leptonic decays
Multi-lepton signatures appear in many new physics searches at the Large Hadron Collider. We here consider WWZ production with subsequent leptonic decay of the three vector bosons as a SM source of multi-lepton events. We have calculated the next-to-leading order QCD corrections for the full pp → 6 lepton production cross sections in hadronic collisions. Results have been implemented in the for...
متن کاملDiffractive production of Drell-Yan pairs and heavy flavors
Partonic interpretation of high-energy reactions is known to depend on a reference frame. Particularly, in the rest frame of the target Drell-Yan process looks like a freeing of the projectile ll̄ fluctuation, rather than qq̄ → ll̄ annihilation. The lightcone representation for Drell-Yan reaction is very similar to that in DIS and exposes a substantial contamination of soft interactions which turn...
متن کاملNLO Electroweak Corrections to Higgs Boson Production at
Results for the complete NLO electroweak corrections to Standard Model Higgs production via gluon fusion are included in the total cross section for hadronic collisions. Artificially large threshold effects are avoided working in the complex-mass scheme. The numerical impact at LHC (Tevatron) energies is explored for Higgs mass values up to 500 GeV (200 GeV). Assuming a complete factorization o...
متن کاملQCD corrections to FCNC single top production at HERA
We calculate first-order QCD corrections to the cross section for single top quark production mediated by flavor changing neutral currents (FCNC) in ep collisions at the HERA collider. We find that the uncertainty due to the choice of the QCD scale is significantly reduced. This study is motivated by the current experimental work for limits on the FCNC single top cross section. On leave of abse...
