Proton spin structure and quark-parton model
The alternative to the standard formulation of the quark-parton model is proposed. Our approach is based on the solution of the master equations relating the structure and distribution functions, which consistently takes into account the intrinsic quark motion in contradistinction to the standard infinite momentum approach, in which this motion is latently suppressed. The model well reproduces ...
متن کاملProton spin structure from measurable parton distributions.
We present a systematic study of the proton spin structure in terms of measurable parton distributions. For a transversely polarized proton, we derive a polarization sum rule from the leading generalized parton distributions appearing in hard exclusive processes. For a longitudinally polarized proton, we obtain a helicity decomposition from well-known quark and gluon helicity distributions and ...
متن کاملElastic Parton-Parton Scattering from AdS/CFT
Using the AdS/CFT correspondence and the eikonal approximation, we evaluate the elastic parton-parton scattering amplitude at large N and strong coupling gN in N=4 SYM. We obtain a scattering amplitude with a Regge behavior that unitarizes at large √ s. For partons with masses m in the range √ s > m > √ −t, we suggest that our results may be of relevance to QCD in four dimensions. E-mail: rho@s...
متن کاملStructure signatures in proton scattering from 9,11Li.
The optical potential and observables for proton-Li elastic scattering are calculated microscopically using the single scattering approximation to the Kerman-McManus-Thaler multiple scattering expansion. The importance of the central and spin-orbit terms of the optical potential, and of the core and halo nucleon contributions, is clarified in terms of the momentum space behaviors of the nucleon...
متن کاملParton distributions of the proton.
To obtain improved parton densities of the proton, we present a new global analysis of deep inelastic and related data including, in particular, the recent measurements of F2 at HERA, of the asymmetry of the rapidity distributions of W production at the FNAL pp̄ collider and of the asymmetry in Drell-Yan production in pp and pn collisions. We also incorporate data to determine the flavour depend...
