NNLO coefficient functions of Higgs and Drell–Yan cross sections in Mellin space
We calculate the Mellin moments of next-to-next-to-leading order coefficient functions of the Drell-Yan and Higgs production cross sections. The results can be expressed in term of finite harmonic sums which are maximally threefold up to weight four. Various algebraic relations among these finite sums reduce the complexity of the results suitable for fast numerical evaluations. It is shown that...
متن کاملThe Drell - Yan Process and Factorization in Impact Parameter Space ∗
The cross section for Drell-Yan pair production in the limit of small xtarget is derived in the rest frame of the target hadron. Our calculation is based on the fundamental quantity σ(ρ), the cross section for the scattering of a qq̄-pair with fixed transverse separation ρ off a hadronic target. As in deep inelastic scattering the result can be given in terms of integrals of σ(ρ). This is consis...
متن کاملInitial State Interactions , Factorization , and the Drell - Yan Process
We show that initial state interactions violate the factorization conjecture for the Drell-Yan process order by order in perturbation theory. We also discuss the effects of elastic and inelastic initial state interactions on the observed cross sections. A Talk Presented by G. T. Bodwin at the 1981 Banff Summer School on Particles and Fields Alberta, Canada, August 16-28, 1981 * Work supported b...
متن کاملCross Sections, Error Bars and Event Distributions in Simulated Drell-yan Azimuthal Asymmetry Measurements
A short summary of results of recent simulations of (un)polarized Drell-Yan experiments is presented here. Dilepton production in pp, ¯ pp, π − p and π + p scattering is considered, for several kinematics corresponding to interesting regions for experiments at GSI, CERN-Compass and RHIC. A table of integrated cross sections, and a set of estimated error bars on measurements of azimuthal asymmet...
متن کاملBeam thrust cross section for Drell-Yan production at next-to-next-to-leading-logarithmic order.
At the LHC and Tevatron strong initial-state radiation (ISR) plays an important role. It can significantly affect the partonic luminosity available to the hard interaction or contaminate a signal with additional jets and soft radiation. An ideal process to study ISR is isolated Drell-Yan production, pp → Xℓ+ ℓ- without central jets, where the jet veto is provided by the hadronic event shape bea...
