The H * H π form factor for H = B and D mesons is evaluated in a QCD sum rule calculation. We study the Borel sum rule for the three point function of two pseudoscalar and one vector meson currents up to order four in the operator product expansion.

We evaluate the form factor at the H* Hπ vertex, for H = B and D mesons, in a QCD sum rule calculation. We study the momentum dependence of the form factor and conclude that it is not compatible with a monopole form. We use two different approaches

The masses of the negative parity $\mathrm{SU}(6)$ 70-plet baryons are analyzed in the ${1/N}_{c}$ expansion to order ${1/N}_{c}$ and to first order in $\mathrm{SU}(3)$ breaking. At this level of precision there are 20 predictions. Among them there a
