COMPASS is a fixed target experiment at the CERN SPS.
The COMPASS physics programme is dedicated to the study of the nucleon spin structure and of hadron spectroscopy. The nucleon spin structure is investigated by means of Deep Inelastic Scattering reactions, using a 160GeV muon beam, impinging on a solid state target. The recent results on the gluon contribution to the nucleon spin, on the...

Verra discussa una misura della sezione d'urto per la produzione inclusiva di fotoni diretti isolati , basata su 880nb-1. La misura copre i range di pseudorapidita' |eta| < 1.37 e 1.52 |eta | < 1.81 per energie trasverse 15 < ET < 100 GeV. I risultati sono confrontati con predizioni di calcoli di QCD perturbativa a NLO. Inoltre saranno presentati i risultati preliminari per il canale a 2...

The study of electromagnetic nucleon form factors is object of
experimental and theoretical studies since decades. At moderate
values of the momentum transfer squared, q^2, the individual
determination of the electric and magnetic FFs strongly constrain
the nucleon models, whereas at larger q^2 the validity of analyticity
and of the asymptotic properties predicted by QCD can be...
