Preface
This book has been written as part of my habilitation at the University of Hamburg.
It is intended to serve graduate students and researchers to get familiar with the stateof-the-art of jet substructure at the LHC. I have attempted to provide enough details
such that this book can serve as a work of reference for experienced researchers as
well.
The versatility of this branch of particle physics is reflected in multi-faceted
developments of algorithms and their numerous applications in measurements and
searches for new phenomena. While this versatility is the reason for the success
of this field, the inexperienced researcher may feel lost when first exposed to this
wealth of information. I advise researchers starting in this area to read the whole
book without stopping at passages which may not be immediately clear at first. After
having obtained a good overview of the possibilities jet substructure methods offer,
re-reading the book will help to deepen the knowledge and reinforce connections.
I hope that the level of detail given will help more experienced researchers to find
solutions to their problems or connections to other areas. I have tried to provide
as many relevant references as possible, to aid the interested reader in finding all
information needed to delve deeply into every topic discussed in this book.
My scientific work, leading to this book, would not have been possible without the
support of Prof. Johannes Haller (University of Hamburg), who has encouraged me to
proceed with my habilitation at the Institute for Experimental Physics. I am grateful
to Dr. Alberto Orso Maria Iorio (INFN Napoli), who has led the physics analysis
group “Beyond Two Generations” within the CMS Collaboration together with me
from 2017 to 2019. The work with this group has inspired me and led to exciting
new developments. I would also like to thank my CMS collaborators for the excellent
working atmosphere and stimulating environment. I have profited from the scientific exchange at numerous conferences and workshops, most notably at the annual
BOOST conference (International Workshop on Boosted Object Phenomenology,
Reconstruction and Searches in HEP).
I am thankful for financial support by the German Bundesministerium für Bildung
und Forschung (BMBF) and the Deutsche Forschungsgemeinschaft (DFG, German
Research Foundation) under Germany’s Excellence Strategy—EXC 2121 “Quantum
Universe”. I am grateful to Prof. Thomas Müller (KIT Karlsruhe) for making the
