Download or read book A Search for Flavour Changing Neutral Current Processes in Decays of Charmed Mesons written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutral current interactions are known from studies of K meson decays to conserve flavor to a high precision. Although flavor changing neutral currents (FCNC) are forbidden in the Weinberg-Salam model, many extensions of the Standard Model allow such processes. We present preliminary upper limits on FCNC-mediated decays of charmed particles, namely D° .-->. ee−, D° .-->. .mu.mu.−, D° .-->. .mu.e and D+ .-->. .pi.+.mu.e.
