Confinement and scaling in deep inelastic scattering.
We show that parton confinement in the final state generates large 1/Q2 corrections to Bjorken scaling, thus leaving less room for the logarithmic corrections. In particular, the x-scaling violations at large x are entirely described in terms of power corrections. For treatment of these non-perturbative effects, we derive a new expansion in powers of 1/Q2 for the structure function that is free...
متن کاملScaling and Diffraction in Deep Inelastic Scattering
We pursue the hypothesis that the events with a large rapidity gap, observed at HERA, reflect the scattering of electrons off lumps of wee partons inside the proton. A simple scaling behaviour is predicted for the diffractive structure functions, which are related to the inclusive structure function F2(x,Q ) at small values of the scaling variable x. The results are compared with recent measure...
متن کاملThe BFKL-Regge Phenomenology of Deep Inelastic Scattering
We calculate the Regge trajectories of the subleading BFKL singularities and eigenfunctions for the running BFKL pomeron in the color dipole representation. We obtain a viable BFKL-Regge expansion of the proton structure function F2p(x,Q ) in terms of several rightmost BFKL singularities. We find large subleading contributions to F2p(x,Q ) in the HERA kinematical region which explains the lack ...
متن کاملINELASTIC ELECTRON SCATTERING AND THE MULTI - REGGE MODEL t
We investigate the multi-Regge model in the kinematic region where the four momentum of one initial particle is large and spacelike. These kinematics occur in inelastic electron scattering through single virtual photon exchange. We predict a rapid fall off in the cross section as the virtual particle becomes more spacelike, contradicting present data. (Submitted to Phys . Rev. ) t Supported by ...
متن کاملScaling Variable for Nuclear Shadowing in Deep-Inelastic Scattering∗
A new scaling variable is introduced in terms of which nuclear shadowing in deepinelastic scattering is universal, i.e. independent of A, Q2 and x. This variable can be interpreted as a measure of the number of gluons probed by the hadronic fluctuations of a virtual photon during their lifetime. The shadowing correction grows at small x substantially less steeply than is suggested by the eikona...
