The E2/M1 and C2/M1 ratios and form factors in N -> Delta transitions
L. Tiator, D. Drechsel, O. Hanstein +2
A partial wave analysis of pion photoproduction has been obtained in the framework of fixed-t dispersion relations valid from threshold up to 500 MeV. In the resonance region we ha…
Helicity Amplitudes and Sum Rules for Real and Virtual Photons
Lothar Tiator
Results of the recently developed unitary isobar model (MAID) are presented for helicity amplitudes, spin asymmetries, structure functions and relevant sum rules for real and virtu…
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…
Measurement of the recoil polarization in the p (\vec e, e' \vec p) pi^0 reaction at the Δ(1232) resonance
Th. Pospischil, P. Bartsch, D. Baumann +39
The recoil proton polarization has been measured in the p (\vec e,e'\vec p) pi^0 reaction in parallel kinematics around W = 1232 MeV, Q^2 = 0.121 (GeV/c)^2 and epsilon = 0.718 usin…
The GDH Sum Rule and Related Integrals
D. Drechsel, S. S. Kamalov, L. Tiator
The spin structure of the nucleon resonance region is analyzed on the basis of our phenomenological model MAID. Predictions are given for the Gerasimov-Drell-Hearn sum rule as well…
gamma* N -> Delta transition form factors: a new analysis of the JLab data on p(e,e'p)pi0 at Q^2=2.8 and 4.0 (GeV/c)^2
S. S. Kamalov, S. N. Yang, D. Drechsel +2
Recent JLab data of the differential cross section for the reaction p(e,e'p)pi0 in the invariant mass region of 1.1 < W < 1.4 GeV at four-momentum transfer squared Q^2= 2.8 and 4.0…
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…
