Description

SMOG2 is a gaseous fixed-target system implemented upstream of LHCb, allowing the experiment to simultaneously collect events from proton-proton collisions and unpolarized proton-gas fixed-target collisions in a kinematic domain that has been poorly explored before.

SMOG2 must be upgraded to enable polarized fixed-target collisions at LHCb, the only way to open this new frontier at LHC. The project is called LHCspin and is an official LHCb R\&D project, planning to be installed at LHCb during Run~5 of the LHC.

During this talk, the ongoing analysis of SMOG2 data in the Drell-Yan channel and the importance of its study to probe quark TMDs will be presented along with the future perspective within the LHCspin project, including its experimental set-up and current hardware development.
