Description

We have studied the production of ground and excited axial charmonia in processes, ee+hc(nP)+ηc(nS), and ee+χc1(nP)+hc(nP) [1] for n,n=1,2, through leading order (LO) tree-level diagrams O(αemαs), which proceed through exchange of a virtual photon and an internal gluon line connecting two quark lines in the triangle quark loop part of the diagram at center of mass energy, s=10.6GeV . We employ the framework of 4×4 Bethe-Salpeter equation, and calculate their cross sections [1], which are compared with recent NRQCD and Relativistic quark model calculations. For both the above processes, we have drawn plots of total cross sections versus s for n,n=1,2, as well as plots of differential cross section versus cosΘ at different center of mass energies. These studies might be of interest for future experiments at B-factories, since hc,ηc, and χc1,hc production might provide opportunities for observing hc with higher statistics in future. Also our cross sections may provide guidance for future experiments at B-factories.
