We discus mechanism of double χc production with large rapidity separation. The first order pertubative correction to gg→χcχc process includes additional emission of gluon among χc pair. We have considered real gluon distribution as well as virtual correction to the production process of χc pairs. Results for two scalar χc0χc0 and two axial mesons χc1χc1 are shown.
