Belle II (Experimental Particle Physics)
The Belle II detector, currently under construction, in 2018 will collect billions of e+ e- collisions produced at the SuperKEKB collider at the KEK laboratory in Tsukuba, Japan. The experiment is designed to record data with a performance similar or better than Belle or BaBar, the B-factory detectors, in a much more severe beam background environment. The B-factory experiments observed the first large signals for CP violation (matter-antimatter asymmetries) in the B meson sector, and demonstrated that the Cabibbo-Kobayashi-Maskawa's hypothesis for the origin of the CP violation is correct providing the experimental foundation for the 2008 Nobel Prize in Physics. Belle II, the first super B-Factory experiment, is designed to find New Physics beyond the Standard Model of particle physics.
The Belle II Torino research activities are focused on:
- Building the laser calibration system for the Time-Of-Propagation detector (TOP), aimed at performing high precision particle identification by means of Cherenkov light
- Perform physics studies involving quarkonium spectroscopy, new physics in rare decays of B, D mesons and tau lepton, and search for Dark Matter in the light sector
- Implement a cloud computing infrastructure for the distributed computing of the experiment
