In Tables 7 and 8, we have determined the decay constants of the pseudoscalar and vector B and D mesons obtained from (53) and (54) in comparison with the results of other recent works.
In addition, the ratio of decay constants for D mesons is ([mathematical expression not reproducible]).
The Borel transformed QCD sum rules had also been used to study the properties of pseudoscalar D mesons [19] and vector mesons, [rho], [omega], and [phi] [17].
For example, in [18] the mass splitting between pseudoscalar D and [bar.D] mesons was investigated using the even and odd QCD sum rules whereas in [19, 23, 24] the mass-shift of D mesons was investigated under centroid approximation.
In literature the properties of kaons and antikaons, D mesons and charmonium had been studied at finite temperature of the nuclear matter using the above mentioned scalar fields a, [zeta], and [chi] [7, 8, 12, 13, 34].

Because the results of the experiments should be available by next summer, some lattice-QCD theorists are rushing to apply their new methods to D mesons and to publish predictions of decay rates and other parameters that the Cornell-based team will measure.
