| Publication Abstract: | We present a projection study for the first moments of the inclusive spin structure function $\int g_1(x,Q^2) \, dx$ for the proton and neutron from simulated doubly-polarized $\vec{e}\vec{p}$ and $\vec{e}$-$^3 \overrightarrow{\rm He}$ collision data expected from the Electron-Ion collider. For detection and extraction of the neutron spin asymmetries from $\vec{e}$-$^3 \overrightarrow{\rm He}$ collisions, we used the double-tagging method which significantly reduces the uncertainty over the traditional inclusive method. Using the Bjorken sum rule, the projected results allow us to determine that the QCD coupling at the $Z$-pole $\alpha_s(M_{Z^0}^2)$ can be measured with a relative precision of $1.3\%$. This underscores the significance of the EIC for achieving precision determinations of $\alpha_s$. |
