Towards the NNLO evolution of polarised parton distributions
We report on the first calculation of the structure function g1 in polarised deep-inelastic scattering to the third order in massless perturbative QCD. The calculation follows the dispersive approach already used for the corresponding unpolarised cases of F2,L, but additionally involves higher tensor integrals and the Dirac matrix γ5 in D = 4 dimensions. Our results confirm all known two-loop e...
متن کاملNonuniversality of transverse momentum dependent parton distributions at small x.
We study the universality issue of the transverse momentum dependent parton distributions at small x, by comparing the initial and final state interaction effects in di-jet-correlations in pA collisions with those in deep inelastic lepton-nucleus scattering. We demonstrate the nonuniversality by performing an explicit calculation in a particular model where the multiple gauge boson exchange con...
متن کاملParton Distributions at High X
We extract the ratio of the down (d) and up (u) parton distribution functions (PDF’s) from the ratio of NMC deuteron and proton structure function F d 2 /F p 2 , using corrections for nuclear binding effects in the deuteron, which are extracted from the nuclear dependence of SLAC F2 data. Significant corrections to the d quark distribution in standard PDF’s are required, especially at high x. T...
متن کاملAnalytic solutions of QCD evolution equations for parton cascades inside nuclear matter at small x.
An analytical method is presented to solve generalized QCD evolution equations for the time development of parton cascades in a nuclear environment. In addition to the usual parton branching processes in vacuum, these evolution equations provide a consistent description of interactions with the nuclear medium by accounting for stimulated branching processes, fusion and scattering processes that...
متن کاملNon-linear Evolution and Parton Distributions at Low X
We suggest a new procedure for extrapolating the parton distributions from HERA to much higher energies. The procedure suggested consists of two steps. First, we solve the non-linear evolution equation. Second, we introduce a correcting function for which we write a DGLAP-type linear evolution equation. The nonlinear equation is solved numerically and estimates for the saturation scale, as well...
