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…
Pion electroproduction on the nucleon and the generalized GDH sum rule
L. Tiator, D. Drechsel, S. S. Kamalov
Results of the recently developed unitary isobar model (MAID) are presented for the spin asymmetries, structure functions and relevant sum rules in the resonance region. The model…
Pion Electroproduction on the Nucleon and the Generalized GDH Sum Rule
L. Tiator, D. Drechsel, S. S. Kamalov
We present predictions for the spin structure functions of the proton and the neutron in the framework of a unitary isobar model for one-pion photo- and electroproduction. Our resu…
New Insights into the Coupling of and Mesons to the Nucleon
M. Kirchbach, L. Tiator, S. Neumeier +1
We show that the contact couplings of neutral pseudoscalar and axial mesons to the nucleon are proportional to , the fraction of nucleon spin carried by the strange quark sea,…
Meson Photo- and Electroproduction
Lothar Tiator
Photo- and electroproduction of pions and eta-mesons is studied on the nucleon. The formalism of such reactions is presented including polarization degrees of freedom and theoretic…
