New physics at a super flavor factory

An invited review article New physics at a Super Flavor Factory was published in Reviews of Modern Physics (Rev. Mod. Phys. 81, 1887-1941) by Jure Zupan from the Faculty of Mathematics and Physics and the "Jo┼żef Stefan" Institute together with collaborators T. Browder (Univ. of Hawaii), T. Gershon (Univ. of Warwick), D. Pirjol (National Institute for Physics and Nuclear Engineering, Bucharest) and A. Soni (Brookhaven National Laboratory).

Super Flavor Factories are a new generation of high precision experiments that will look at rare decays of B mesons and tau leptons. The aim is to look for new particles through their quantum effects on the decays. There are two proposals for the experiments, one in KEK, Japan (with a strong Slovenian
participation), the other in Frascati, Italy. They would accumulate two orders of magnitude more data than the present generation of "B factory" experiments. Under relatively conservative assumptions this means that the effects of new particles with 500 GeV to TeV masses can be seen (if they for instance contribute at 1-loop order and are minimally flavor violating). This is also the range of mass scales that the experiments at the CERN Large Hadron Collider will probe in the next decade, but the dependence on the couplings and masses in the Super Flavor Factory processes is different. Furthermore, if couplings do not exhibit the minimal structure, mass scales of above 100 TeV can be probed as well.
