SEESAW 25 : proceedings of the International Conference on the Seesaw Mechanism : Institut Henri Poincaré, Paris, 10-11 June 2004

This volume reviews the progress of the Seesaw mechanism since its invention 25 years ago, as well as presents the recent theoretical developments in the understanding of the observed pattern in neutrino masses and mixings. Observable implications of the seesaw mechanism like leptogenesis or lepton flavor violation in supersymmetric theories are addressed, and the key aspects of the vast experimental program aimed at determining the neutrino parameters and properties are also reviewed. The book provides an up-to-date and in-depth perspective on neutrino masses. CONTENTS......Page 10 Foreword......Page 6 1. Introduction......Page 12 3. Old & New Puzzles......Page 13 5.
