摘要：

The invariant-mass distribution of the hadronic state in tau-decay can be used for testing fundamental aspects of the strong interactions. Using standard QCD techniques, it is possible to compute certain weighted integrals of the hadronic spectrum. We work out some QCD predictions which will be useful for analysing the data. They provide a direct way to simultaneously measure alpha(s)(m(tau)2) and the parameters characterizing the non-perturbative dynamics, allowing for a better control of the theoretical errors in the determination of alpha(s)(m(tau)2).
