The LHCSpin Project

Not scheduled
Strong interactions (perturbative and non-perturbative QCD, DIS, heavy ions)


LHCSpin aims at installing a polarized gas target in front of the LHCb spectrometer, bringing, for the first time, polarized physics to the LHC. The project will benefit from the experience achieved with the installation of an unpolarized gas target at LHCb during the LHC Long Shutdown 2. LHCb will then become the first experiment simultaneously running in collider and fixed-target mode with polarized targets, opening a whole new range of explorations to its exceptional spectrometer. LHCSpin will offer a unique opportunity to probe polarized quark and gluon parton distributions in nucleons and nuclei, especially at high $x$ and intermediate Q$^2$, where experimental data are still largely missing. Beside standard collinear parton distribution functions (PDFs), LHCSpin will make it possible to study multidimensional polarized parton distributions that depend also on parton transverse momentum (transverse-momentum-dependent PDFs, or TMDs). LHCSpin stands out at the moment as the most promising project, going beyond the kinematic coverage and the accuracy of the existent experiments, especially on the heavy-quark sector.
