SuperB particle-accelerator project launches

Funding uncertainty could delay high-speed Italian development.

Nicola Nosengo

The SuperB factory, a particle accelerator to be built on the campus of the University of Rome Tor Vergata over the next six years, was officially launched on Friday. But the project faces uncertain funding and competition from a Japanese project.

The accelerator will be what physicists call a B-factory, where electrons and their antiparticles, positrons, will race around two 1.3-kilometre-long rings, then collide and produce heavy B mesons. By studying the way these particles decay, physicists hope to fill some of the gaps in the standard model of physics, such as why there is more matter than antimatter in the Universe, and whether the exotic particles predicted by the theory of supersymmetry really exist… (continua a leggere su
