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…
A dispersive approach to pion photo- and electroproduction
D. Drechsel, B. Pasquini, L. Tiator
The relativistic amplitudes of pion photo- and electroproduction are calculated by dispersion relations at constant t. Several sum rules and low-energy theorems for the threshold a…
Proton spin polarizabilities from polarized Compton scattering
B. Pasquini, D. Drechsel, M. Vanderhaeghen
Polarized Compton scattering off the proton is studied within the framework of subtracted dispersion relations for photon energies up to 300 MeV. As a guideline for forthcoming exp…
Observables in Unpolarized and Polarized Virtual Compton Scattering
A. Metz, B. Pasquini, D. Drechsel
Below pion threshold virtual Compton scattering off the nucleon gives access to the generalized electromagnetic polarizabilities. Different theoretical results for the generalized…
