First results from COMPASS — •Lars Schmitt — TU München, Physik-Department E18, D-85747 Garching

COMPASS is a fixed-target experiment running with a 160 GeV muon beam at CERN’s SPS accelerator. It is aimed at the study of the nucleon spin structure using a polarized muon beam and a polarized ⁶LiD target.

In a second phase, a hadronic beam will be used to investigate charmed hadrons and hadrons with gluonic degrees of freedom, to study Primakov and diffractive scattering and to search for exotic states.

The status of the ongoing analysis of gluon polarization via asymmetries in D-meson and high-p_T hadron pair production will be presented. In addition preliminary results on Λ polarisation, exclusive vector meson production, and other topics will be summarized.
