Flavor Data Constraints on the SUSY Parameter Space
We present an overview of the indirect constraints from flavor physics on supersymmetric models. During the past few years flavor data, and in particular b → sγ transitions, have been extensively used in order to constrain supersymmetric parameter spaces. We will briefly illustrate here the constraints obtained by a collection of low energy observables including FCNC transitions, rare decays, l...
متن کاملSpace Carving on 3D Graphics Hardware
We describe fast voxel coloring using programmable 3D graphics hardware based on texture mapping capabilities of modern graphics accelerators. In contrast to previous approaches, where graphics hardware is only partially employed to speed up voxel coloring, our implementation performs the reconstruction procedure entirely on the graphics processing unit. Therefore, any expensive transfer of dat...

متن کاملOn the Performance Characterization of Stereo and Space Carving
The performance evaluation of 3-D reconstruction techniques is not a simple problem to solve. This is not only due to the increased dimensionality of the problem but also due to the lack of standardized and widely accepted testing methodologies. This paper presents characterization to the performance of two standard 3-D reconstruction techniques; stereo and space carving. The evaluation is perf...
متن کاملPositivity constraints in QCD
The density matrix positivity is a natural counterpart of unitarity. The resulting constraints for various parton distribution and correlations are considered. Their compatibility with leading order QCD evolution is guaranteed by the probabilistic interpretation of the latter. In the case of non-forward distributions the positivity constraints naturally imply the symmetric form of the evolution...
