We report on a search for the flavor-changing neutral current decay D0 → μ+μ− using 50 × 106 events recorded with a dimuon trigger in interactions of 920GeV protons with nuclei by the HERA-B experiment. We find no evidence for such decays and set a 90% confidence level upper limit on the branching fraction B(D0 → μ+μ−) < 2.0 × 10−6.

In this paper is proposed a hybrid face detector that combines the high processing speed of an Asymmetrical Adaboost Cascade Detector with the high detection rate of a Wavelet Bayesian Detector. This integration is achieved by incorporating this last detector in the middle stages of the cascade detector. Results of the application of the proposed detector to a standard face detection database a...
