Particles, Strings and the Early Universe
The Structure of Matter and Space-Time
von Michael Grefe, herausgegeben von Johannes HallerWithin the Collaborative Research Centre SFB 676 “Particles, Strings and the Early Universe: The
Structure of Matter and Space-Time” funded by the German Research Foundation (DFG), scientists
of Universit¨at Hamburg and DESY have performed research at the interface of mathematical physics,
particle physics and cosmology. Started in June 2006, the SFB 676 has approached its completion in
June 2018, after a maximum funding period of 12 years. During these years, the research areas of the
SFB have seen tremendous progress on many fronts, highlighted by the scientific breakthroughs of the
discovery of the Higgs boson in 2012 and the first observation of gravitational waves in 2015.
In this book, we take the opportunity to review the scientific achievements and research highlights
obtained in the context of the SFB 676, the current state and the perspectives of the respective fields.
The content of the book reflects the organisational structure of the SFB 676 with its three research areas:
A) String Theory, B) Particle Physics and C) Cosmology. The individual chapters have been contributed
by the principal investigators and other key researchers of the various sub-projects whom we would
like to thank for their contributions, for their commitment, and for their brilliant research work during
the course of the SFB. In addition to the involved local scientists, many guest researchers whom we
welcomed in Hamburg provided essential contributions to the research of the SFB.
The success of the SFB 676 would not have been possible without the help of many people in the
administration and management. We would like to thank in particular Marco Baumgartl, Elizabeth
Duarte, Holger Enderle, Manfred Fleischer, Irmgard Flick, Daniel Gildenhorn, Frank Laubert, Juan
Mercado, Natalia Potylitsina-Kube, Harald Schl¨uter and Department 4 of Universit¨at Hamburg, Lilija
Seskute, and Peter Siebeneichner. Very special thanks go to our closest companions Michael Grefe,
Petra Hinzer, andWiebke Kircheisen, who have strongly shaped this SFB over the years with their savvy
and clever ideas and initiatives, their unbreakable enthusiasm, and their indispensable help. In addition,
we are of course grateful to the DFG for their help and support during the last 12 years, in particular we
would like to thank Brit Red¨ohl. Last but not least, we acknowledge the continuous enormous support
of our two hosting institutions in Hamburg: Universit¨at Hamburg and DESY.
