摘要
Some higher twist corrections to the Bjorken sum rule are estimated in the framework of a quark-diquark model of the nucleon. The parameters of the model have been previously fixed by fitting the measured higher twist corrections to the unpolarized structure function F-2(x, Q(2)). The resulting corrections to the Bjorken sum rule turn out to be negligible.
