From the reviews Physics with Tau Leptons provides a firm basis in theory, in measurement techniques, and in summaries of known results for making full use of recent improvements in quantity and quality of data on the tau. The book will be useful for younger researchers in the field, who don know the history of the hundreds of tau measurements, ... Read moreas well as for older researchers who have forgotten that history. The book will also be interesting and useful to those who work on the physics of the electron, the muon, or their neutrinos, as well as for those who are searching for heavier leptons. Physics with Tau Leptons belongs in the physics libraries of all universities and research laboratories. Those who have it in their personal libraries will treasure its comprehensiveness and clarity. Achim Stahl's beautifully written and comprehensive book, Physics with Tau Leptons, comes at a most opportune time for tau physics. Martin L.
