Paul Langacker is an Emeritus Professor of Physics and Astronomy at the University of Pennsylvania. He is currently a Senior Scientist at Princeton University and a long-term visitor at the Institute for Advanced Study. His research has emphasized the connections between fundamental theory and experiment, and has included work in precision electroweak physics, grand unification, neutrino physics, Z’ physics, and string phenomenology.

"The textbook by Paul Langacker gives a comprehensive…overview about the Standard Model of Elementary Particle Physics and beyond…. the full Standard Model including mathematical foundations and current experimental references is fully reviewed. After each chapter, the reader finds quite an extensive set of problems which allows [them] to deepen the previously learned knowledge…The book is clearly not intended to serve theorists in their daily life but rather an experimental physicist to understand the theory behind and perform some simple calculations. However, as a kind of compendium and standard reference it is a worthy tool for everybody in the field."—Wolfgang G. Hollik (Hamburg) in Zentralblatt MATH 1376."The 2009 first edition of The Standard Model and Beyond provided a long-needed and thorough introductory textbook that focused on the advances in phenomenology that led to the highly successful Standard Model of Elementary Particle Physics. Its author, Paul Langacker, is well known not only for his research, but also his communication skills both as a lecturer and writer. However, much has happened over the last seven years, as the Higgs scalar was discovered, thus completing the minimal spectrum of the Standard Model, whilst the field of neutrino physics continued to mature. At the same time, a number of leading speculations regarding ‘new physics’, beyond the Standard Model, failed to be observed, causing a re-examination of some beliefs. This newly updated second edition explores such constraints on ‘new physics’ ideas, in addition to exploring recent discoveries and advances in the field. The text remains lucid, thorough, and well-worth having, and so I strongly recommend it as a resource for students and researchers who wish to understand, and help continue, the legacy of scientific exploration and discovery."—William J.
