Abstract:
We present a summary update of the QCD spectral sum rule (QSSR) results for the running and {\it perturbative pole} quark masses, the fDf_D and fBf_B leptonic decay constants, the heavy-to-light and heavy-to-heavy transition-form factors. Analytic expressions of these latter quantities are presented, which give a deeper understanding of their q 2q~2- and infinite mass-behaviours.
