Description
COMPASS is a fixed target high energy physics experiment that has been collecting data for 20 years (2002 to 2022) at the M2 beamline (SPS, North Area) at CERN. One of the goals of the experiment's broad physics program was to perform semi-inclusive measurements of target-spin dependent asymmetries in (di-)hadron production in DIS with high-energy muons colliding with polarised targets. The latest COMPASS semi-inclusive DIS measurements were performed in 2022 using a transversely polarised deuteron target and a 160 GeV/$c$ muon beam. They balance the existing data collected with transversely polarised proton targets and thus play a crucial role in constraining the d-quark transversity and Sivers functions.
This talk will present first results from about two thirds of the new 2022 data.
