    A recent global QCD analysis of jet production and other polarized scattering data has found the presence of negative solutions for the gluon helicity distribution in the proton, Δ⁢𝑔, along with the traditional Δ⁢𝑔>0 solutions. We consider polarized semi-inclusive deep-inelastic scattering for hadrons produced with large transverse momentum as a means of constraining the dependence of Δ⁢𝑔 on the parton momentum fraction, 𝑥. Focusing on the double longitudinal spin asymmetry, we identify the kinematics relevant for future experiments at Jefferson Lab and the Electron-Ion Collider that are particularly sensitive to the polarized gluon channel and could discriminate between the different Δ⁢𝑔 behaviors. We find that a ∼20  GeV beam at the high luminosity Jefferson Lab may be especially well-suited for discriminating between the positive and negative solutions.
