Analysis of deuteron spin structure by statistical model

The inclusive longitudinal spin asymmetry of deuteron A1d has been evaluated using Thermodynamical Bag Model (TBM) within the experimental range 0.002<x<0.7 with 1<Q2<100 GeV2. The spin-dependent structure function g1d employed in our estimation is used to derive the spin asymmetry of the deuteron A1d. The obtained theoretical evaluations are compared with experimental results of COMPASS and SMC. The evaluated results are in agreement with those from previous parameterized evaluations and improve considerably the statistical accuracy in the region 0.003<x<0.05.
