Parton distributions : a new global analysis
We present a new analysis of parton distributions of the proton. This incorporates a wide range of new data and an improved treatment of heavy flavours and prompt photon production. The new set (MRST) shows systematic differences from previous sets of partons which can be identified with particular features of the new data and with improvements in the analysis. We also investigate the sensitivi...
متن کاملGlobal QCD Analysis of Parton Distributions
Recent global QCD analyses of high energy lepton-hadron and hadron-hadron interactions are reviewed. New data on asymmetries in Drell-Yan and W-lepton-asymmetry processes contribute to better determine the d=u ratio; while improved experimental data on inclusive jet production, in conjunction with precise deep inelastic scattering data, place good constraints on the gluon over a wide range of x...
متن کاملTowards a global analysis of polarized parton distributions
We present a technique for implementing in a fast way, and without any approximations, higher-order calculations of partonic cross sections into global analyses of parton distribution functions. The approach, which is set up in Mellin-moment space, is particularly suited for analyses of future data from polarized proton-proton collisions, but not limited to this case. The usefulness and practic...
متن کاملGlobal Fits of Parton Distributions
The fundamental quantities one requires in the calculation of scattering processes involving hadronic particles are the parton distributions. Global fits [1]-[7] use all available data, largely structure functions, and the most up-todate QCD calculations, currently NLO–in–αs(Q ), to best determine these parton distributions and their consequences. In the global fits input partons are parameteri...
متن کاملGlobal QCD analysis and the CTEQ parton distributions.
The CTEQ program for the determination of parton distributions through a global QCD analysis of data for various hard scattering processes is fully described. A new set of distributions, CTEQ3, incorporating several new types of data is reported and compared to the two previous sets of CTEQ distributions. Comparison with current data is discussed in some detail. The remaining uncertainties in t...
