With the Large Hadron Collider (LHC) now under construction, a review of LHC phenomenology becomes timely and important. In chapters contributed by leading researchers, this book explores the technology and physics associated with the LHC, from searches for the Higgs boson and physics beyond the standard model to detailed studies of quantum chromodynamics and the properties of hadronic matter at high energy density. It informs readers about the basic properties and capabilities of the machine, detectors, and software required for physics analyses. Each chapter provides a tutorial-style introduction to the topic under discussion and is written at a level suitable for readers with a basic knowledge of high-energy physics.
