Abstract

After a short introduction to the physics of COMPASS and the description of the spectrometer, the RICH-1 upgrade project is presented within the performed laboratory activities. Also the preliminary results of the performances of the new RICH-1 are illustrated. The focus then moves on the analysis of the data, and taking advantage of the upgraded RICH-1, the Collins and the Sivers asymmetries, extracted from the data collected during the transverse run of 2007, are presented both for unidentified and identified hadrons.
