SSP2012 - 5th International Symposium on Symmetries in Subatomic Physics

The LHCb experiment carries out precision measurements of CP asymmetries in the heavy quark sector in order to look for signs of physics beyond the Standard Model. If present, new physics amplitudes can interfere with SM processes and affect CP asymmetry observables such that they might deviate from predicted CKM values. The LHCb program includes a wide search for CP observables in different...

Although CP violation in the B-meson system has been well established by the B factories, there has been no direct observation of time-reversal violation in this system. Using 468 million B-Bbar pairs collected by the BABAR detector at SLAC, we measure T-violating parameters in the time evolution of neutral-B mesons by comparing the probabilities of B0 or anti-B0 transforming into definite CP...

The decays B -> tau nu, B -> D tau nu, and B -> D* tau nu are sensitive to physics beyond the standard model, in particular to contributions from charged Higgs bosons. The multiple-neutrino final states make studies of these decays particularly challenging and require reconstruction of the full event, which can be performed only at an electron-positron collider. We use the full BABAR data set...

With an integrated luminosity goal larger than 75 ab-1, the SuperB factory is expected to be built on the Tor Vergata campus near Rome Italy by 2016. Its goal is to unravel the detailed structure of the new physics likely to be discovered at the LHC, and to explore BSM physics beyond the direct reach of the LHC. These goals will be achieved through the study of a wide variety of rare B, charm...
