Quark Rearrangement and Annihilation Model for Formula N Annihilation at 0 300 MeV

Abstract

For the S, P and D wave PP annihilations at 0 ∼300 MeV we consider quark rearrangement process into three mesons and qq annihilation process into two mesons, where the mesons are the SU(6) s- and p- wave mesons. Most of major branching ratios are qualitatively described. The quark rearrangement prosess dominates in the S wave annihilation.
