Longitudinal spin dependence of massive lepton pair production
نویسنده
چکیده
I show that massive lepton-pair production, the Drell-Yan process, should be a good source of independent constraints on the polarized gluon density, free from the experimental and theoretical complications of photon isolation that beset studies of prompt photon production. I provide predictions for the spin-averaged and spin-dependent differential cross sections as a function of transverse momentum QT at energies relevant for the Relativistic Heavy Ion Collider (RHIC) at Brookhaven.

Constraints on the Proton ’ S Gluon Density from Lepton - Pair Production Edmond
Massive lepton-pair production, the Drell-Yan process, should be a good source of independent constraints on the gluon density, free from the experimental and theoretical complications of photon isolation that beset studies of prompt photon production. We provide predictions for the spin-averaged and spin-dependent differential cross sections as a function of transverse momentum Q T .
متن کاملAspects of four-jet production in polarized proton-proton collisions.
We examine the intrinsic spin-dependence of the dominant gg → gggg subprocess contribution to four-jet production in polarized proton-proton collisions using helicity amplitude techniques. We find that the partonic level, longitudinal spin-spin asymmetry, âLL, is intrinsically large in the kinematic regions probed in experiments detecting four isolated jets. Such events may provide another qual...
متن کاملProbing Relativistic Spin Effects in the Nucleon by Means of Drell–Yan Processes
Significant differences between transverse and longitudinal polarized parton distributions are found at low energies within a light-front covariant quark model of the nucleon. These differences are due to relativistic spin effects introduced by the Melosh rotations and survive evolution to higher Q2 scales. We show that the importance of these relativistic effects can be assessed by measuring d...
متن کاملPolarized antiquark flavor asymmetry in Drell – Yan pair production
We investigate the role of the flavor asymmetry of the nucleon's polarized antiquark distributions in Drell–Yan lepton pair production in polarized nucleon–nucleon collisions at HERA (fixed–target) and RHIC energies. It is shown that the large polarized antiquark flavor asymmetry predicted by model calculations in the large–N c limit (chiral quark–soliton model) has a dramatic effect on the dou...
متن کاملA 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
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.
