The J/ψ D D vertex in QCD sum rules
- 1. Sao Paulo Univ., SP (Brazil). Inst. de Fisica
Description
The J/ψ D D form factor is evaluated in a QCD sum rule calculation for both D and J/ψ off-shell mesons. We study the double Borel sum rule for the three point function of the two pseudoscalar and one vector meson current. We find that the momentum dependence of the form factors is different if the D or the J/ψ meson is off-shell, but they lead to the same coupling constant in the J/ψ D D vertex. (author)
