Polarized Deep Inelastic Scattering

The target mass effects in polarized DIS have been studied. It was demonstrated that taking into account the first-order target mass corrections to g1 a very good approximation of the exact formula is achieved. It was also shown that their magnitude in the pre-asymptotic DIS region is small except for x > 0.65, where their large effect is partially suppressed by the large values of Q2 due to the cut W2 > 4 GeV 2. The difference between the size of the target mass and higher twist corrections is illustrated.
