Conformal string operators and evolution of skewed parton distributions
نویسندگان
چکیده
We have investigated skewed parton distributions in coordinate space. We found that their evolution can be described in a simple manner in terms of non-local, conformal operators introduced by Balitsky and Braun. The resulting formula is given by a Neumann series expansion. Its structure resembles, for all values of the asymmetry parameter, the well-known solution of the ERBL equation in the momentum space. Performing Fourier transformation we have reproduced known results for evolution of momentum-space distributions. work supported in part by BMBF Alexander von Humboldt fellow

Conformal string operators and skewed parton distributions
We discuss skewed parton distributions in the coordinate space. Solution of the corresponding LO evolution equation is constructed in terms of eigenfunctions of the evolution kernel and its relation to the conformal symmetry is explained.

We briefly discuss the problem of specifying initial conditions for evolution of off-diagonal (skewed) parton distributions. We present numerical results to show that evolution rapidly washes out differences of input. Off-diagonal (or skewed) parton distributions provide important information about the nonper-turbartive structure of the nucleon [ 1]. They can in principle be measured in such pr...
متن کاملInitial conditions and evolution of off - diagonal distributions
Off-diagonal (or skewed) parton distributions provide important information about the nonperturbartive structure of the nucleon [1]. They can in principle be measured in such processes as deeply virtual Compton scattering, diffractive vector meson production or diffractive high-pT jet production. Just as for the ordinary (diagonal) parton distributions, the QCD evolution equations [2] play an i...
متن کاملExploring Skewed Parton Distributions with Polarized Targets
I brie y review the physics of skewed parton distributions. Special emphasis is put on the relevance of target polarization, and on the di erent roles of small and of intermediate xB. 1 The physics of skewed parton distributions In recent years much progress has been made in the theory of skewed parton distributions (SPDs). Unifying the concepts of parton distributions and of hadronic form fact...
متن کاملSkewed parton distributions and the scale dependence of the transverse size parameter
We discuss the scale dependence of a skewed parton distribution of the pion obtained from a generalized light-cone wave function overlap formula. Using a simple ansatz for the transverse momentum dependence of the light-cone wave function and restricting ourselves to the case of a zero skewedness parameter the skewed parton distribution can be expressed through an ordinary parton distribution m...
