| dc.description.abstract | In this thesis we employ Bethe Salpeter Equation(BSE) under Covariant Instanta- neous Ansatz(CIA) to calculate: (A) The cross section of double Charmonium pro- duction from electron-positron annihilation at the CM energy 10:6GeV through the process e++e ! J= + c, which has recently been observed at B factories and whose measurements were done by Babar and Belle groups. (B) The decay width for the ra- diative decay of equal mass vector mesons through the process h ! h0 + (h=vector meson, h'=pseudoscalar meson and =the emitted photon.) (C) Decay width for strong decay of excited vector mesons through the process h ! h0 + h"(h=excited vector meson, h'=vector meson and h"=pseudoscalar meson.) The calculated results are in reasonable agreement with data | en_US |
