“…The absence of flavor-changing neutral currents (FCNCs) in kaon decays led to the prediction of the charm quark [1], and the observation of B 0 ÿ B 0 mixing, a FCNC process, signaled the very large top-quark mass [2]. To date, rare and forbidden charm decays have been less informative and less extensively studied.…”

Using 0:8 10 6 D D ÿ pairs collected with the CLEO-c detector at the 3770 resonance, we have searched for flavor-changing neutral current and lepton-number-violating decays of D mesons to final states with dielectrons. We find no indication of either, obtaining 90% confidence level upper limits of B D ! e e ÿ < 7:4 10 ÿ6 , B D ! ÿ e e < 3:6 10 ÿ6 , B D ! K e e ÿ < 6:2 10 ÿ6 , and B D ! K ÿ e e < 4:5 10 ÿ6 .

The BaBar high energy physics experiment will be in operation at the PEP-II asymmetric e + e − collider in Spring 1999. The primary purpose of the experiment is the investigation of CP violation in the neutral B meson system. The electromagnetic calorimeter forms a central part of the experiment and new techniques are employed in data acquisition and reconstruction software to maximise the capability of this device.The use of a matched digital filter in the feature extraction in the front end electronics is presented. The performance of the filter in the presence of the expected high levels of soft photon background from the machine is evaluated.The high luminosity of the PEP-II machine and the demands on the precision of the calorimeter require reliable software that allows for increased physics capability. BaBar has selected C++ as its primary programming language and object oriented analysis and design as its coding paradigm. The application of this technology to the reconstruction software for the calorimeter is presented. The design of the systems for clustering, cluster division, track matching, particle identification and global calibration is discussed with emphasis on the provisions in the design for increased physics capability as levels of understanding of the detector increase.The CP violating channel B o → J/ΨK o s has been studied in the two lepton, two π 0 final state. The contribution of this channel to the evaluation of the angle sin 2β of the unitarity triangle is compared to that from the charged pion final state. An error of 0.34 on this quantity is expected after 1 year of running at design luminosity.
