On the Scaling Violations of Diffractive Structure Functions: Operator Approach
نویسندگان
چکیده
A quantum field theoretic treatment of inclusive deep–inelastic diffractive scattering is given. The process can be described in the general framework of non–forward scattering processes using the light–cone expansion in the generalized Bjorken region. Evolution equations of the diffractive hadronic matrix elements are derived at the level of the twist– 2 contributions and are compared to those of inclusive deep–inelastic forward scattering (DIS). The diffractive parton densities are obtained as projections of two–variable parton distributions. We also comment on the higher twist contributions in the light–cone expansion.

Polarized Deep Inelastic Diffractive ep Scattering: Operator Approach
Polarized inclusive deep–inelastic diffractive scattering is dealt with in a quantum field theoretic approach. The process can be described in the general framework of non–forward scattering processes using the light–cone expansion in the generalized Bjorken region applying the generalized optical theorem. The diffractive structure functions g D(3) 1 and g D(3) 2 are calculated in the twist–2 a...
متن کاملSemiclassical Approach to Structure Functions at Small x
Inclusive and diffractive structure functions for electron-proton scattering are calculated in a semiclassical approach at large momentum transfer Q2 and small values of the scaling variable x. The basic process is the production of a quark-antiquark pair in the colour field of the proton. The structure functions are expressed in terms of Wilson lines along the classical trajectories of quark a...
متن کاملPolarized Deep Inelastic Diffractive Scattering near the Light Cone
Inclusive unpolarized and polarized deeply inelastic diffractive scattering at high energies and momentum transfer is one of the important processes in lepton–nucleon scattering. As found by experiment, cf. [1], there are interesting relations between the cross sections of these processes and those of inclusive deeply inelastic scattering: i) the scaling violations of both processes are quite s...
متن کاملDetermination of αS from scaling violations of truncated moments of structure functions
We determine the strong coupling αS(MZ) from scaling violations of truncated moments of the nonsinglet deep inelastic structure function F2. Truncated moments are determined from BCDMS and NMC data using a neural network parametrization which retains the full experimental information on errors and correlations. Our method minimizes all sources of theoretical uncertainty and bias which character...
متن کاملBuchmüller Scaling, the QCD Pomeron, and Tevatron Diffractive Hard Scattering
We discuss the observed scaling of the small-x diffractive and total deepinelastic structure functions at HERA. We argue that the parton interpretation of Buchmüller and Hebecker can be understood within QCD as the appearance of the Pomeron in a Super-Critical phase. In diffractive hard scattering, the Pomeron appears as reggeized gluon exchange in a color-compensating background field. The for...
