Opis

This book introduces the reader to the field of jet substructure, starting from the basic considerations for capturing decays of boosted particles in individual jets, to explaining state-of-the-art techniques. Jet substructure methods have become ubiquitous in data analyses at the LHC, with diverse applications stemming from the abundance of jets in proton-proton collisions, the presence of pileup and multiple interactions, and the need to reconstruct and identify decays of highly-Lorentz boosted particles. The last decade has seen a vast increase in our knowledge of all aspects of the field, with a proliferation of new jet substructure algorithms, calculations and measurements which are presented in this book.  Recent developments and algorithms are described and put into the larger experimental context. Their usefulness and application are shown in many demonstrative examples and the phenomenological and experimental effects influencing their performance are discussed. A comprehensive overview is given of measurements and searches for new phenomena performed by the ATLAS and CMS Collaborations. This book shows the impressive versatility of jet substructure methods at the LHC.

O autorze

Roman Kogler studied physics at the University of Technology in Vienna. He obtained his PhD in 2010 for research performed at the Max-Planck Institute Munich with the H1 experiment at the HERA collider. During his time as DESY post-doctoral fellow, he deepened his knowledge on jet physics and measurements of fundamental parameters. He joined the University of Hamburg in 2012, where he lectures on elementary particle physics, statistics and detector physics. As a member of the CMS Collaboration, his research focusses on the development of jet substructure techniques and their application in measurements and searches for new phenomena.
