Precision physics in Hadronic Tau Decays / Rodriguez-Sanchez, Antonio
In the Standard Model of Particle Physics, which gives a very precise description of nature at many different scales, hadronic tau decays occur through the interaction of two weak charged currents mediated by the W boson, so it becomes a very nice test of electroweak interactions [...]
