Description
The COMPASS experiment has taken data from 2002 to 2022, at the CERN SPS. A consistent part of the data taking has been dedicated to SIDIS measurements with 160 GeV muon beam and longitudinally and transversely polarized targets. In these years many results have been produced, in particular for transverse spin asymmetries, and have been used for extractions of the transversity and the Sivers functions. For this phenomenological work, it turned out clearly that the statistics of the existing deuteron and neutron data were too scarce and that more data were needed. For this reason, COMPASS dedicated the last year of data taking to SIDIS off transversely polarized deuteron. The data taking was successful, and the data analysis is going on at high speed. Many measurements are expected from this data, and first results will be shown here.
