Analysis of deuteron spin structure by statistical model

The inclusive longitudinal spin asymmetry of deuteron image has been evaluated using Thermodynamical Bag Model (TBM) within the experimental range image with image. The spin-dependent structure function image employed in our estimation is used to derive the spin asymmetry of the deuteron image. 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 image.
