Some electromagnetic properties of the nucleon from Relativistic Chiral Effective Field Theory
Vladimir Pascalutsa
Considering the magnetic moment and polarizabilities of the nucleon we emphasize the need for relativistic chiral EFT calculations. Our relativistic calculations are done via the f…
Magnetic moment of the Delta(1232)-resonance in chiral effective field theory
Vladimir Pascalutsa, Marc Vanderhaeghen
We perform a relativistic chiral effective field theory calculation of the radiative pion photoproduction () in the -resonance region, to next-to-leading order…
The shape of the nucleon
Franz Gross, Peter Agbakpe
We show that all four of the nucleon form factors can be very well explained using the manifestly covariant spectator theory. The nucleon is modeled as a spherical state of three c…
Pion photoproduction on nucleons in a covariant hadron-exchange model
Vladimir Pascalutsa, John A. Tjon
We present a relativistic dynamical model of pion photoproduction on the nucleon in the resonance region. It offers several advances over the existing approaches. The model is obta…
Form Factors from a Relativistic Dynamical Model of Pion Electroproduction
G. L. Caia, V. Pascalutsa, J. A. Tjon +1
We obtain the electromagnetic form factors of the transition by analyzing recent pion-electroproduction data using a fully relativistic dynamical model. Special care is taken…
