چکیده
We study the flavor-changing-neutral-current process c-->u micro(+) micro(-) using 1.3 fb(-1) of pp[over ] collisions at square root s = 1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We see clear indications of the charged-current mediated D(s)(+) and D(+)-->phipi(+) --> micro(+)micro(-)pi(+) final states with significance greater than 4 standard deviations above background for the D(+) state. We search for the continuum neutral-current decay of D(+)-->pi(+) micro(+) micro(-) in the dimuon invariant mass spectrum away from the phi resonance. We see no evidence of signal above background and set a limit of B(D(+) --> pi(+) micro(+) micro(-))<3.9 x 10(-6) at the 90% C.L. This limit places the most stringent constraint on new phenomena in the c--> u micro(+) micro(-) transition.

Search for Rare Charm Meson Decays at FNAL E 791
We report the results of a blind search for flavor-changing neutral current (FCNC), lepton-flavor violating, and lepton-number violating decays of D, D s , and D 0 mesons (and their antiparticles) into 2–, 3–, and 4–body states including a lepton pair. Such decays may involve Flavor-Changing Neutral Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No evidence for any of th...

This report summarizes the latest experimental results on radiative and electroweak rare B meson decays. These rare decay processes proceed through the Flavor-Changing-Neutral-Current processes, and thus are sensitive to the postulated new particles in the theories beyond the Standard Model. Experiments at e + e − colliders, Belle, BaBar and CLEO, have been playing the dominant role, while the ...
متن کاملEffects of Littlest Higgs model in rare D meson decays
A tree-level flavor changing neutral current in the up-like quark sector appears in one of the variations of the Littlest Higgs model. We investigate the effects of this coupling in the D → πll and D → ρll decays, which are the most appropriate candidates for the experimental studies. However, the effects are found to be too small to be observed in the current and the foreseen experimental faci...
متن کاملStudy of Rare B Meson Decays at Belle
In this paper, we briefly review results on rare decays of B mesons from the Belle experiment, based on 10.4 fb−1 data collected on the Υ(4S) resonance. The topics include measurements of Cabibbo suppressed decays B → D(∗)K(∗), charmless twobody decays B → ππ, Kπ, KK and B → η′h (h = K+, π+,K0), and a search for flavor changing neutral current decays B → K(∗)l+l−. To appear in the Proceedings o...
متن کاملSearch for the Flavor - Changing Neutral Current Decay D 0 → μ + μ − with the HERA - B Detector
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.
متن کاملPhenomenology of Neutral D − meson Decays and Double - Flavor Oscillations 1 Ya
Decays of neutral D-mesons are considered phenomenologically without invoking any particular models. Special attention is given to cascade decays with intermediate neutral kaons where coherent double-flavor oscillations (CDFO) become possible. We show necessity and unique possibilities of experiments on CDFO. They allow to relate with each other widths and masses of D-meson eigenstates, to sepa...
