Nonlocal operators and distribution amplitudes of definite twist, WW-like relations, BC-like sum rules and power corrections for hard QCD processes
Bodo Geyer, Markus Lazar, Dieter Robaschik
The decomposition of nonlocal operators (and of their matrix elements) into an (infinite) series w.r.t. geometric twist is used to introduce (new) parton distributions, generalized…
Influence of the pseudogap on the superconductivity-induced phonon renormalization in high-T superconductors
S. Varlamov, G. Seibold
We investigate the influence of a d-density wave (DDW) gap on the superconductivity-induced renormalization of phonon frequency and linewidth. The results are discussed with respec…
On the structure of the virtual Compton amplitude with additional final-state meson in the extended Bjorken region
Johannes Blümlein, Jörg Eilers, Bodo Geyer +1
Using the framework of the non-local light-cone expansion a systematic study is performed for the structure of the twist-2 contributions to the virtual Compton amplitude in polariz…
Power corrections of off-forward quark distributions and harmonic operators with definite twist
Bodo Geyer, Markus Lazar, Dieter Robaschik
A group theoretical procedure for parametrizing non-forward matrix elements of non-local QCD operators is introduced. The related (two-variable) distribution amplitudes are given a…
On the Scaling Violations of Diffractive Structure Functions: Operator Approach
J. Blümlein, D. Robaschik
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 pro…
Effective interactions in the stripe state of the two-dimensional Hubbard model
S. Varlamov, G. Seibold
We investigate the structure of the pairing potential in the stripe phase of the two-dimensional Hubbard model. Based on the random phase approximation we discuss in detail the int…
Dynamical charge susceptibility in layered cuprates: the influence of screened inter-site Coulomb repulsion
M. Eremin, I. Eremin, S. Varlamov
The analytical expression for dynamical charge susceptibility in layered cuprates has been derived in the frame of singlet-correlated band model beyond random-phase-approximation (…
