| Sumario: | The COMPASS experiment at CERN is studying the nucleon spin structure with a 160 GeV polarized anion beam and polarized targets as well as hadron structure with 190 GeV pion, kaon and proton beams. The paper gives an overview of the results for the helicity and transverse spin structure of the nucleon. A first result from the spectroscopy experiments, the observation of a resonance with exotic $J^{PC} =$ 1$^{-+}$ quantum numbers at 1660 MeV is also presented. The paper ends with an outlook to future measurements. |
