High Energy Physics Seminar
The B Factory experiments BaBar and Belle established CP violation in the B meson system and enabled to put tight experimental constraints on the quark-flavor sector of the Standard Model. The excellent confirmation of the theory predictions by BaBar and Belle led to the Nobel Prize in physics for Makoto Kobayashi and Toshihide Maskawa in 2008.
The new accelerator SuperKEKB and the Belle 2 detector are currently in intensive preparations at KEK in Japan. SuperKEKB is designed to operate at an instantaneous luminosity of 8x10^35/cm^2/s, which is a factor 40 higher than that of KEKB. The upgraded Belle 2 detector will collect data samples two orders of magnitudes larger than those of the BaBar and Belle experiments. Belle 2 will enable to perform studies of heavy flavor decays governed by quantum-loop effects at unprecedented precision.
In this talk, the Belle 2 experiment and its physics program will be introduced. The experimental prospects to flavor observables sensitive to new physics effects are being presented. The anomalies reported recently by BaBar, Belle and LHCb in diverse decay modes will be included in the discussions.
