"Version: 20180701"--Title page verso.Includes bibliographical references (pages 24-26).Introduction -- The Standard Model and quantum chromodynamics -- Hadrons and the quark model -- Different types of hadrons -- Background -- Understanding hadrons through their quantum numbers -- Discovery of the J/[psi] meson -- Resonances, Breit-Wigner lineshape and phase changes -- Controversy over claimed light pentaquarks -- Heavy flavour hadrons, and the experimental facilities used to study them -- Discovery of the X(3872) -- Current directions -- Tetraquarks -- Pentaquarks -- Doubly heavy baryons -- Outlook -- Models of exotic hadrons and how they can be distinguished -- Experimental prospects.Since 2003 there has been an explosion in the observation of new hadronic states that cannot be classified by the well-tested quark model of mesons (quark-antiquark) and baryons (three quarks or antiquarks). The properties of these states indicate that they are combinations of four, five, or more, quarks and antiquarks, making them manifestly exotic. A recent high-profile example was the discovery of two pentaquark candidates by the LHCb collaboration at the CERN Large Hadron Collider (LHC). No scientific consensus has yet emerged to explain the exotic hadron spectrum, demanding a new set of experimental observations that will feed the development of theoretical models to describe the dynamics of multiquark states. In this Discovery book we will take you on a tour of quantum chromodynamics, explain about the latest research into the physics of exotic hadrons and describe the exciting opportunities that are offered by the next generation of particle physics experiments.Final-year undergraduates, new PhD students and early-career scientists.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Greig Cowan is a particle physicist at the University of Edinburgh. Prior to the start of the CERN Large Hadron Collider (LHC) he deployed and commissioned the grid computing infrastructure that now underpins the success of the LHC physics programme. Since 2010 he has been a member of the LHCb collaboration at CERN, focussing on measuring the subtle differences between matter and antimatter in the physics of b quarks (so-called CP violation), searching for new states in the exotic hadron spectrum and measuring the properties of those that have been found. From 2013-2018 he was an Ernest Rutherford research fellow, funded by the UK's Science and Technology Facilities Council (STFC). Tim Gershon is a Professor of Physics at the University of Warwick. After completing his PhD at the University of Cambridge in 2000, his research career has taken him to experiments in Japan and California as well as CERN. He served as Physics Coordinator for the LHCb experiment for the calender years 2012 and 2013. In addition to work on hadron spectroscopy, he is highly active in studies of CP violation in the B system.Title from PDF title page (viewed on August 8, 2018).
