Pion Generalized Parton Distributions with covariant and Light-front constituent quark models
T. Frederico, E. Pace, B. Pasquini +1
We investigate the model dependence of no-helicity flip generalized parton distribution of the pion upon different approaches for the quark-hadron and quark-photon vertexes, in the…
Azimuthal spin asymmetries in light-cone constituent quark models
S. Boffi, A. V. Efremov, B. Pasquini +1
We present results for all leading-twist azimuthal spin asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering due to T-even transverse-momentum dependent parton di…
Structure of the Nucleon Spin on the Light Cone
B. Pasquini
The spin structure of the nucleon is studied in a light-cone description of the nucleon where the Fock expansion is truncated to consider only valence quarks. Transverse momentum d…
Transverse-momentum distributions in a diquark spectator model
A. Bacchetta, F. Conti, M. Radici
All the leading-twist parton distribution functions are calculated in a spectator model of the nucleon, using scalar and axial-vector diquarks. Single gluon rescattering is used to…
Mini-review on Monte Carlo programs for Bhabha scattering
G. Balossini, C. Bignamini, C. M. Carloni Calame +3
We review the status of Monte Carlo generators presently used for simulations of the large-angle Bhabha process at electron-positron colliders of moderately high energy (flavour fa…
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…
