The series Advances in the Physics of Particles and Nuclei (APPN) is devoted to the archiving
in printed high-quality book format of the comprehensive long shelf-life reviews published in
The European Physical Journal A and C. APPN will be of benefit in particular to those
librarians and research groups who have chosen to have only electronic access to these
journals. Occasionally original material in review format and refereed by the series'
editorial board will also be included. The three reviews collected in this volume summarize and
document the outcome of the year long work by the CERN working groups studying the role of
flavor physics in the era of the LHC. They confirm that flavor physics is an essential element
in the future of high-energy physics. Should new-physics particles be produced at the LHC
studies of flavor physics will play a key role helping to find the underlying new-physics
scenario to study the properties of new-physics particles and to detect or to exclude new
sources of CP violation and flavor structures.
