Growth in the particle zoo
In Search of the Secret of Tetraquark and CoRead out
The smallest building blocks of matter give up puzzles - today more than ever. For just in recent years, physicists have discovered some subatomic particles that do not fit into the usual scheme. These include particles with four or even more quarks. How these particles come about and how they are structured has so far been open - and the subject of intensive research.
The scientists who have discovered several of these exotic particles include the physicists around Ulrich Wiedner of the Ruhr-Universität Bochum. They try to track down these multi-quark particles by electron-positron collisions at the BES-III experiment in China. But a new particle accelerator in Darmstadt could also help solve the particle puzzle in the future.
