Climate change is triggered by a too high concentration of greenhouse gases in the air, carbon dioxide in particular, primarily originating from fossil fuel-burning. Since such burning will not stop any time soon, the concentration will undoubtedly r

We show that contrary to recent claims the QCD sum rules for charmonium remain unchanged when dimension-six and-eight operators are included. These results explain the remarkable accuracy of the mass determinations.

In this paper we present in a detailed and coherent fashion our work on QCD sum rules for equal mass heavy quark meson states. We discuss the technical procedures used to calculate the perturbative and non-perturbative contributions to the vacuum pol

Sets of coupled sum rules are analyzed for heavy quark hybrids. In the exotic 1 −+ channel not a single sum rule stabilizes while in other channels the results are self-consistent.

We review the theoretical basis and the applications to hadronic physics of the QCD sum rules invented by Shifman, Vainshtein and Zakharov.

We calculate coupling constants in QCD by extrapolating from the asymptotic freedom regime using QCD sum rules. The novel feature is that these amplitudes are dominated by the quark condensate when one leg is a pseudoscalar Goldstone boson. We find m
