TL;DR
This paper explores the potential of the AFTER@LHC fixed-target experiment to measure single-transverse-spin asymmetries in heavy quarkonium and open-charm production, achieving high precision unattainable elsewhere.
Contribution
It proposes using a polarized hydrogen target at AFTER@LHC to perform novel, high-precision spin asymmetry measurements in heavy flavor production.
Findings

Unique capability of the fixed-target setup at LHC for spin physics
Feasibility of measuring asymmetries in open-charm and bottomonium production
Abstract
We discuss the potential of AFTER@LHC to measure single-transverse-spin asymmetries in open-charm and bottomonium production. With a HERMES-like hydrogen polarised target, such measurements over a year can reach precisions close to the per cent level. This is particularly remarkable since these analyses can probably not be carried out anywhere else
