摘要：
We calculate the off-forwaxd structure function of the pion within a simple model where the size of the pion is accounted for using a momentum cut-off. Twist-two and twist three generalized parton distributions are extracted. Relations between twist-three and twist-two contributions are obtained, the origin of which is not kinematical as they differ from those arising from the Wandzura-Wilczek approximation.
