dc.descriptionVery recently, a new measurement of the deuteron spin-dependent structure function $g_1^d (x)$ was reported by the COMPASS group. A main change from the old SMC measurement is a considerable improvement of the statistical accuracy in the low $x$ region $0.004 < x < 0.03$. We point out that the new COMPASS data for $g_1^d (x)$ as well as their QCD fits for $ΔΣ$ and $Δs + Δ\bar{s}$ are all remarkably close to our theoretical predictions given several years ago based on the chiral quark soliton model.
