Azimuthal dependence in diffractive processes
M. Diehl
Azimuthal distributions in high-energy processes give information about the helicity structure of diffractive reactions. I discuss predictions of several dynamical mechanisms in th…
Summary of Working Group B: Diffraction and Vector Mesons
A. Bruni, M. Diehl, F. -P. Schilling
We summarise the contributions presented in working group B: "Diffraction and Vector Mesons" at the 12th Intl. Workshop on Deep Inelastic Scattering (DIS 2004) held in Strbske Ples…
Diffraction, exclusive processes, and proton structure in three dimensions
M. Diehl
I briefly review how a three-dimensional picture of parton dynamics is rendered in the impact parameter representation, applied to generalized parton distributions and to the dipol…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
Designer mesons for exploring factorization in b decays
M. Diehl
I explain how various aspects of factorization in exclusive b decays can be studied with mesons having a small decay constant or spin greater than one.
The photon-pion transition form factor for virtual photons
M. Diehl, P. Kroll, C. Vogt
We discuss the photon to meson transition form factor for virtual photons, which can be measured in e+ e- collisions. We demonstrate that this form factor is independent of the sha…
