Nuclear Shadowing and the Optics of Hadronic Fluctuations
G. Piller, M. Vänttinen, L. Mankiewicz +1
A coordinate space description of shadowing in deep-inelastic lepton-nucleus scattering is presented. The picture in the laboratory frame is that of quark-gluon fluctuations of the…
Coherence Effects in Diffractive Electroproduction of rho Mesons from Nuclei
T. Renk, G. Piller, W. Weise
A systematic multiple scattering formalism for vector meson electroproduction from nuclei is developed, with emphasis on the formation, propagation and hadronization scales for qua…
Exclusive meson production at COMPASS
Josef Pochodzalla, Lech Mankiewicz, Murray Moinester +3
We explore the feasibility to study exclusive meson production (EMP) in hard muon-proton scattering at the COMPASS experiment. These measurements constrain the off-forward parton d…
Resonances and higher twist in polarized lepton-nucleon scattering
J. Edelmann, G. Piller, N. Kaiser +1
We present a detailed analysis of resonance contributions in the context of higher twist effects in the moments of the proton spin structure function g_1. For each of these moments…
Nuclear Deep-Inelastic Lepton Scattering and Coherence Phenomena
Gunther Piller, Wolfram Weise
This review outlines our present experimental knowledge and theoretical understanding of deep-inelastic scattering on nuclear targets. The emphasis is primarily on nuclear coherenc…
Comments on Exclusive Electroproduction of Transversely Polarized Vector Mesons
L. Mankiewicz, G. Piller
We discuss the electroproduction of light vector mesons from transversely polarized photons. Here QCD factorization cannot be applied as shown explicitly in a leading order calcula…
