Electromagnetic Excitation of Nucleon Resonances
L. Tiator, D. Drechsel, S. S. Kamalov +1
Recent progress on the extraction of electromagnetic properties of nucleon resonance excitation through pion photo- and electroproduction is reviewed. Cross section data measured a…
Nucleon Polarizabilities: Theory
B. Pasquini, D. Drechsel, M. Vanderhaeghen
We review recent developments in the theoretical investigation of the nucleon polarizabilities. We first report on the static polarizabilities as measured in real Compton scatterin…
Higher order forward spin polarizability
B. Pasquini, P. Pedroni, D. Drechsel
As a guideline for future experiments to extract the four (leading) spin polarizabilities of the nucleon, we have constructed the forward amplitude for polarized Compton scattering…
Reply to "Comment on `The polarizability of the pion: no conflict between dispersion theory and chiral perturbation theory'"
B. Pasquini, D. Drechsel, S. Scherer
We reply to the Comment by Fil'kov and Kashevarov, arXiv:0805.4486 [hep-ph]. We show that the discrepancies between ChPT and dispersion theory, reported for the polarizability of t…
The polarizability of the pion: no conflict between dispersion theory and chiral perturbation theory
B. Pasquini, D. Drechsel, S. Scherer
Recent attempts to determine the pion polarizability by dispersion relations yield values that disagree with the predictions of chiral perturbation theory. These dispersion relatio…
Invariant Amplitudes for Pion Electroproduction
B. Pasquini, D. Drechsel, L. Tiator
The invariant amplitudes for pion electroproduction on the nucleon are evaluated by dispersion relations at constant t with MAID as input for the imaginary parts of these amplitude…
