Effect of absorptive corrections on inclusive parton distributions
نویسنده
چکیده
We study the effect of absorptive corrections due to parton recombination on the parton distributions of the proton. A more precise version of the GLRMQ equations, which account for non-linear corrections to DGLAP evolution, is derived. An analysis of HERA F2 data shows that the small-x gluon distribution is enhanced at low scales when the absorptive effects are included, such that a negative gluon distribution at 1 GeV is no longer required.

We perform a NLO QCD analysis of deep-inelastic scattering data, in which we account for absorptive corrections. These corrections are determined from a simultaneous analysis of diffractive deep-inelastic data. The absorptive effects are found to enhance the size of the gluon distribution at small x, such that a negative input gluon distribution at Q 2 = 1 GeV 2 is no longer required. We discus...

with σ the physical cross section, σ̂ the perturbatively calculable hard scattering factor, and φf/hi the parton distribution for parton f in hadron hi. The partonic hard-scattering factors σ̂ include soft and virtual corrections, arising from soft-gluon emission and loop diagrams, which manifest themselves as plus distributions and delta functions with respect to a kinematical variable xth that ...
متن کاملParton Distributions from Photoproduction in Polarized ep Scattering at HERA
We study photoproduction of jets and single-inclusive hadrons in a polarized ep collider mode of HERA at √ s ≈ 300 GeV, examining the sensitivity of the cross sections and their asymmetries to the proton’s polarized gluon distribution and to the completely unknown parton distributions of polarized photons. We also present for the first time the NLO corrections to the direct part of polarized si...
متن کاملDiffractive Interactions: Theory Summary
There has been an ongoing effort in the last years to describe diffractive DIS within the framework of QCD. Progress has been made in understanding the connections between different approaches, and we have had presentations about modelling the nonperturbative input needed in a QCD description. Soper [ 1] recalled that to leading twist accuracy, i.e. up to corrections in powers of 1/Q, the inclu...
