The 13th International Workshop on Tau Lepton Physics (TAU2014)

14 Sept 2014, 08:00 → 19 Sept 2014, 18:00 Europe/Zurich

RWTH Aachen University

This is the thirteenth workshop of this series devoted to physics of the τ lepton and its associated neutrino. The goal of the workshop is to get theorists and experimentalists together to discuss recent progress in τ lepton physics. New results in τ from high energy machines, low energy machines and B-factories will be presented as well as recent results from g-2 and neutrino oscillation experiments. The program also includes related subjects such as hadron cross section measurement at e⁺e^- colliders, searches for Lepton Flavour Violation in μ decays and review talks on the future experiments.
