/“TMD physics at COMPASS: present and future"/

*Abstract:*


The COMPASS Experiment is a fixed-target spectrometer taking data since 
15 years at the CERN SPS. After a brief mention of the rich and 
diversified physics measurements which have already been performed or 
are being planned, the talk will focus on the variety of physics results 
which have been obtained in the domain of the recently introduced 
transverse momentum dependent (TMD) parton distribution functions by 
semi-inclusive deeply inelastic scattering (SIDIS) of 160 GeV muons off 
transversely polarized proton and deuteron targets. In a complementary 
approach, the first ever Drell–Yan measurement on a transversely 
polarized proton target was the objective of the 2015 run, to address 
the fundamental issue of the change of sign of the Sivers function when 
measured in the Drell–Yan process as compared to that measured in SIDIS.”
