Chiral Perturbation Theory and the first moments of the Generalized Parton Distriputions in a Nucleon
Marina Dorati, Tobias A. Gail, Thomas R. Hemmert
We discuss the first moments of the parity-even Generalized Parton Distributions (GPDs) in a nucleon, corresponding to six (generalized) vector form factors. We evaluate these fund…
The electromagnetic Nucleon to Delta transition in Chiral Effective Field Theory
Tobias A. Gail, Thomas R. Hemmert
We present a calculation of the three complex form factors parametrizing the nucleon to Delta transition matrix element in the framework of chiral effective field theory with expli…
Signatures of chiral dynamics in the Nucleon to Delta transition
Tobias A. Gail, Thomas R. Hemmert
Utilizing the methods of chiral effective field theory we present an analysis of the electromagnetic -transition current in the framework of the non-relativistic "small scale e…
Explicit Delta(1232) Degrees of Freedom in Compton Scattering off the Deuteron
Robert P. Hildebrandt, Harald W. Grießhammer, Thomas R. Hemmert +1
We examine elastic Compton scattering off the deuteron for photon energies between 50 MeV and 100 MeV in the framework of chiral effective field theories to next-to-leading order.…
Spin Polarizabilities of the Nucleon from Polarized Low Energy Compton Scattering
Robert P. Hildebrandt, Harald W. Griesshammer, Thomas R. Hemmert
As guideline for forthcoming experiments, we present predictions from Chiral Effective Field Theory for polarized cross sections in low energy Compton scattering for photon energie…
Signatures of Chiral Dynamics in Low Energy Compton Scattering off the Nucleon
Robert P. Hildebrandt, Harald W. Griesshammer, Thomas R. Hemmert +1
We present a projector formalism which allows to define dynamical polarizabilities of the nucleon from a multipole expansion of the nucleon Compton amplitudes. We give predictions…
