A Light-Front Model for the Transition Distribution Amplitudes for Backward Timelike Compton Scattering
B. Pasquini, A. Schiavi
To access information on the internal structure of the nucleon, data from a variety of scattering experiments can be analyzed, in regimes where the information factorizes from an o…
Two-photon exchange corrections to elastic -proton scattering: Full dispersive treatment of states at low momentum transfers
O. Tomalak, B. Pasquini, M. Vanderhaeghen
We evaluate the pion-nucleon intermediate-state contribution to the two-photon exchange (TPE) correction in the elastic electron-nucleon scattering within a dispersive framework. W…
Compton scattering from chiral dynamics with unitarity and causality
A. M. Gasparyan, M. F. M. Lutz, B. Pasquini
Proton Compton scattering is analyzed with the chiral Lagrangian. Partial-wave amplitudes are obtained by an analytic extrapolation of subthreshold reaction amplitudes computed in…
Light-front transverse charge densities
Cédric Lorcé, Barbara Pasquini, Marc Vanderhaeghen
We discuss the recent interpretation of quark-distribution functions in the plane transverse to the light-cone direction. Such a mapping is model independent and allows one to buil…
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…
Nucleon generalized polarizabilities within a relativistic Constituent Quark Model
B. Pasquini, G. Salme`
Nucleon generalized polarizabilities are investigated within a relativistic framework, defining such quantities through a Lorentz covariant multipole expansion of the amplitude for…
