A dispersion theoretical approach to the threshold amplitudes of pion photoproduction
O. Hanstein, D. Drechsel, L. Tiator
We give predictions for the partial wave amplitudes of pion photoproduction near threshold by means of dispersion relations at fixed t. The free parameters of this approach are det…
Electromagnetic Production of the Hypertriton
T. Mart, L. Tiator, D. Drechsel +1
Kaon photoproduction on He3, gamma + He3 --> K+ + Hypertriton, is studied in the framework of the impulse approximation. Realistic He3 wave functions obtained as solutions of Fadde…
General introduction to Compton scattering
D. Drechsel
Real and virtual Compton scattering has been and will be an important tool to study the structure of hadronic systems. We summarize the status of real Compton scattering and give a…
Dispersion-theoretical analysis of the nucleon electromagnetic form factors: Inclusion of time-like data
H. -W. Hammer, Ulf-G. Meißner, D. Drechsel
We update a recent dispersion--theoretical fit to the nucleon electromagnetic form factors by including the existing data in the time--like region. We show that while the time--lik…
The rare decay in chiral perturbation theory
G. Kn"ochlein, S. Scherer, D. Drechsel
We investigate the rare radiative eta decay modes and within the framework of chiral perturbation theory at . We present photon spectra and pa…
