Query: Neutron Spin Structure from e-3He Scattering with Double Spectator
  Tagging at the Electron-Ion Collider   The spin structure function of the neutron is traditionally determined by
measuring the spin asymmetry of inclusive electron deep inelastic scattering
(DIS) off polarized3He nuclei. In such experiments, nuclear effects can lead to
large model dependencies in the interpretation of experimental data. Here we
study the feasibility of suppressing such model dependencies by tagging both
spectator protons in the process of DIS off neutrons in3He at the forthcoming
Electron-Ion Collider (EIC). This allows reconstructing the momentum of the
struck neutron to ensure it was nearly at rest in the initial state, thereby
reducing sensitivity to nuclear corrections, and suppress contributions from
electron DIS off protonsin3He. Using realistic accelerator and detector
configurations, we find that the EIC can probe the neutron spin structure from
xB of 0.003 to 0.651. We further find that the double spectator tagging method
results in reduced uncertainties bya factor of 4 on the extracted neutron spin
asymmetries over all kinematics, and by a factor of 10 in the low-xB
region,thereby providing valuable insight to the spin and flavor structure of
nucleons
