【Abstract】 We obtain analytic expression for gluon distribution function from Altarelli-Pansi equation by means of the inverse Mellin transformation method in a reasonable approximation. The comparison between theoretical prediction and experimental data is discussed. The behaviour of the gluon distribution is also discussed from this expression.更多还原
