Abstract:
Since many years, one of the prime issues in hadron physics is the
understanding of the nucleons spin from the interplay of its
constituents. Besides possible angular momentum effects gluonic
contributions have been the prime candidate. The COMPASS experiment at
CERN is investigating polarized semiinclusive deep inelastic scattering
to access spin contributions of quarks and gluons. The talk adresses
the physics issues and presents the first physics results from COMPASS.
In addition other physics topics presently under investigation or
planned in the near future are also presented.
