Analysis of angular distributions in gamma N \to pi0 eta N
A. Fix, M. Ostrick, L. Tiator
Angular distributions in the final state of pi0-eta photoproduction on nucleons are considered. As a formal base the familiar isobar model is used in which the (pi0 eta N) state is…
Unitary Isobar Model - MAID2007
D. Drechsel, S. S. Kamalov, L. Tiator
The unitary isobar model MAID2007 has been developed to analyze the world data of pion photo- and electroproduction. The model contains both a common background and several resonan…
Nucleon resonances in πN scattering up to energies \sqrt(s) < 2.0 GeV
Guan Yeu Chen, S. S. Kamalov, Shin Nan Yang +2
A meson-exchange model for pion-nucleon scattering was previously constructed using a three-dimensional reduction scheme of the Bethe-Salpeter equation for a model Lagrangian invol…
Photoproduction of eta-mesons on the deuteron above S11(1535) in the presence of a narrow P11(1670) resonance
A. Fix, L. Tiator, M. V. Polyakov
Incoherent photoproduction of eta-mesons on the deuteron is considered. The main attention is paid to the region above the S11(1535) resonance where rather narrow resonance like st…
Recent progress in pion photo- and electroproduction analysis
L. Tiator, D. Drechsel, S. Kamalov +1
Pion photo- and electroproduction has been studied at threshold and in the resonance region below W=2GeV. At threshold pi^0 production can be very well explained within a dynamical…
Hypernuclear Physics with Photons
C. Bennhold, T. Mart, F. X. Lee +7
We review the opportunities and challenges in the field of hypernuclear physics with electromagnetic probes. An overview is presented regarding our current understanding of the ele…
