SU(3) Breaking in K and K* Distribution Amplitudes
Patricia Ball, M. Boglione
We calculate the decay couplings and first two Gegenbauer moments of the leading twist light-cone distribution amplitudes of K and K* from QCD sum rules, including NLO perturbative…

Towards a model independent determination of the phi -> f_0 - gamma coupling
M. Boglione, M. R. Pennington
A guide to the composition of the enigmatic f_0(980) and a_0(980) states is their formation in phi-radiative decays. Precision data are becoming available from the KLOE experiment…

The full spin structure of quarks in the nucleon
A. Bacchetta, M. Boglione, A. Henneman +1
We discuss bounds on the distribution and fragmentation functions that appear at leading order in deep inelastic 1-particle inclusive leptoproduction or in Drell-Yan processes. The…
