Longitudinal double-spin asymmetry $A_1^{\mathrm{p}}$ and spin-dependent structure function $g_1^{\mathrm{p}}$ of the proton at small values of $x$ and $Q^2$

We present a precise measurement of the proton longitudinal double-spin asymmetry $A_1^{\mathrm{p}}$ and the proton spin-dependent structure function $g_1^{\mathrm{p}}$ at photon virtualitie…
