Abstract
Abstract The s-wave pp annihilation potential is derived from the quark rearrangement model. Combining the G -parity transformed OBEP of Bryan and Phillips and the derived s-wave annihilation potential we solve the multichannel N / D equation by the Pade approximant method. For the p- and d-waves we introduce a phenomenological annihilation potential from a few-meson decay mode. We can reproduce the annihilation cross section by choosing two parameters: the strength of the s-wave annihilation potential and the strength of the p- and d-wave annihilation potential. We find p-wave quasi-bound states near the threshold but their energy and width are sensitive to the energy dependence of the effective phase-space function x ( E ).
