Abstract
In this thesis we employ Bethe Salpeter Equation(BSE) under Covariant Instantaneous Ansatz(CIA) to calculate: (A) The cross section of double Charmonium production from electron-positron annihilation at the CM energy 10:6GeV through the process e++e− ! J= +ηc, which has recently been observed at B factories and whose measurements were done by Babar and Belle groups. (B) The decay width for the radiative decay of equal mass vector mesons through the process h ! h0 + γ(h=vector meson, h’=pseudoscalar meson and γ=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.
