1121por Borsato, Martino“…This thesis presents also a R$\&$D activity on a new detector concept based on the BaBar DIRC, the FDIRC. Its design is intended to operate the detector in an environment with a background two orders of magnitude larger than BaBar thanks to a faster and smaller imaging camera made of radiation-hard fused silica. …”

1125“…These issues have already been investigated and a data model has been proposed and used for different implementations based in commercial DBMSs, both at CERN and for the BaBar experiment. The special case of the ATLAS complex trigger that requires online access to calibration and alignment data poses new challenges that have to be met using a flexible and customizable solution more in the line of Open Source components. …”

1130“…Nevertheless, a number of interesting anomalies have accumulated that can be taken as hints towards new physics: BaBar, Belle, and LHCb have found deviations of approximately 3:8sigma in B -> Dtaunu and B -> D^*taunu; the anomalous magnetic moment of the muon differs by about 3sigma from the theoretic prediction; the branching ratio for tau -> mununu is about 2sigma above the Standard Model expectation; and CMS and ATLAS found hints for a non-zero decay rate of h -> mutau at 2.6sigma. …”

1138por Fleischer, Robert“…Using the branching ratio and direct CP asymmetry of $B^0_d\to\pi^-K^+$, the picture of the direct CP violation in $B_d^0\to\pi^+\pi^-$ could be clarified: we predict $A_{CP}^{dir}(B_d\to\pi^+\pi^-)=-0.24\pm0.04$, which favours the BaBar measurement, and extract $\gamma=(70.0^{+3.8}_{-4.3})^\circ$, in agreement with the Standard-Model fits of the unitarity triangle. …”
