Abstract We calculate the small-momentum expansion of vector, axial-vector, scalar, and pseudo-scalar heavy-quark current correlators in the large-β 0 limit of QCD, extending the analysis of Grozin and Sturm beyond the vector current. Our results ar

We combine ALEPH and OPAL results for the spectral distributions measured in $\tau\to\pi^-\pi^0\nu_\tau$, $\tau\to 2\pi^-\pi^+\pi^0\nu_\tau$ and $\tau\to\pi^-3\pi^0\nu_\tau$ decays with (i) recent BaBar results for the analogous $\tau\to K^- K^0\nu_\

After discussing difficulties in determining αs from tau decay due to the existence of Duality Violations and the associated asymptotic nature of the OPE, we describe a new determination based on an improved vector isovector spectral function, now b

O presente trabalho estudou a influencia dos parâmetros grid , dose threshold e metodos de suavizacao no calculo da distribuicao de dose em feixe de eletrons de 9 MeV no algoritmo eMC, Varian. Para isso, foram calculadas e construidas as curvas de p
