Hard Leptoproduction of Charged Vector Mesons
L. Mankiewicz, G. Piller, T. Weigl
We present an analysis of twist-2, leading order QCD amplitudes for hard exclusive leptoproduction of charged vector mesons. These processes are determined by nonforward parton dis…
Hard Exclusive Meson Production and Nonforward Parton Distributions
L. Mankiewicz, G. Piller, T. Weigl
We present an analysis of twist-2, leading order QCD amplitudes for hard exclusive leptoproduction of mesons in terms of double/nonforward parton distribution functions. After revi…
Analytic Approximation to the GLAP evolution of in the small- region
L. Mankiewicz, A. Saalfeld, T. Weigl
We propose a systematic approximation scheme for solving GLAP evolution equations at small Bjorken-. The approximate solutions interpolate smoothly between hard (singular as $x^…
On the analytical approximation to the GLAP evolution at small x and moderate Q^2
L. Mankiewicz, A. Saalfeld, T. Weigl
Comparing the numerically evaluated solution to the leading order GLAP equations with its analytical small-x approximation we have found that in the domain covered by a large fract…
Combining Lattice QCD Results with Regge Phenomenology in a Description of Quark Distribution Functions
L. Mankiewicz, T. Weigl
The most striking feature of quark distribution functions transformed to the longitudinal distance representation is the recognizable separation of small and large longitudinal dis…
Physically Motivated Approximation to a Parton Distribution Function in QCD
L. Mankiewicz, T. Weigl
It has been suggested that parton distributions in coordinate space, so called Ioffe-time distributions, provide a more natural object for non-perturbative methods compared to the…
