"This book is printed on high-quality paper including many full coloured figures that make it a pleasure to read and extract information out of it. For sure, this collection is a valuable contribution to the literature as no equivalent textbook exists. In summary, this collection is a comprehensive account of the experimental effort in the search for the Higgs boson at the LHC and has the ability to work as a standard reference in the field." Zentralblatt MATH The recent observation of the Higgs boson has been hailed as the scientific discovery of the century and led to the 2013 Nobel Prize in physics. This book describes the detailed science behind the decades-long search for this elusive particle at the Large Electron Positron Collider at CERN and at the Tevatron at Fermilab and its subsequent discovery and characterization at the Large Hadron Collider at CERN. Written by physicists who played leading roles in this epic search and discovery, this book is an authoritative and pedagogical exposition of the portrait of the Higgs boson that has emerged from a large number of experimental measurements. As the first of its kind, this book should be of interest to graduate students and researchers in particle physics.
