Neutron single spin asymmetries from semi-inclusive deep inelastic scattering off transversely polarized He
Sergio Scopetta
A study of semi-inclusive deep inelastic scattering off transversely polarized He is presented. The formal expressions of the Collins and Sivers contributions to the azimuthal…
Generalized parton distributions of few body systems
Sergio Scopetta
The relevance of measuring Generalized Parton Distributions (GPDs) for few nucleon systems is illustrated. An approach which permits to calculate the GPDs of hadrons made of compos…
Generalized parton distributions of hadrons with composite constituents
Sergio Scopetta
A method is described for calculating the Generalized Parton Distributions (GPDs) of spin 1/2 hadrons made of composite constituents, in an Impulse Approximation framework. GPDs ar…
Multi-frequency monitoring of gamma-ray loud blazars: I. Light curves and spectral energy distributions
U. Bach, C. M. Raiteri, M. Villata +23
Context: Being dominated by non-thermal emission from aligned relativistic jets, blazars allow us to elucidate the physics of extragalactic jets, and, ltimately, how the energy is…
REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination
E. Molinari, S. D. Vergani, D. Malesani +32
Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…
Technetium and the third dredge up in AGB stars II. Bulge stars
Stefan Uttenthaler, Josef Hron, Thomas Lebzelter +3
We searched for Technetium (Tc) in a sample of bright oxygen-rich asymptotic giant branch (AGB) stars located in the outer galactic bulge. Tc is an unstable element synthesised via…
