We present results on lepton energy and recoil hadronic mass moments in semileptonic B decay using a total of 9.4 fb^-1 of data taken with the CLEO detector at the \Upsilon(4S). These results are discussed in the context of Heavy Quark…

We present final measurements of thirteen charmless hadronic B decay modes from the CLEO experiment. The decay modes include the ten pipi, Kpi, and KKbar final states and new limits on dibaryonic final states, ppbar, pLambdabar, and…

Studies on the decay and production of $B_c (B^*_c)$ meson are briefly reviewed. Considering RUN-II of Tevatron and the schedule of LHC, the theoretical studies of $B_c$ meson will jump to a new stage not only for itself but also to…

The ALICE experiment is devoted to the study of heavy-ion collisions at the CERN LHC collider. We present the results of a feasibility study for the detection of D^0 \to K^-\pi^+ decays in Pb-Pb collisions with ALICE.

The latest SLD results on light-quark fragmentation and tests of hadronisation models are presented

Based on a data sample of 60 pb-1 collected at the psi(3770) resonance with the CLEO-c detector at CESR, we present improved measurements of absolute branching fractions for exclusive D0 semileptonic decays into K- e+ nu, pi- e+ nu and K*-…

We calculate electromagnetic production from highly excited hadronic matter created in heavy ion collisions. The rates include the usual lowest order processes in quark-gluon plasma plus the usual reactions in the hadronic phase, related…

The study of b-hadrons made possible a great number of benchmark results in flavour physics. In recent years a lot of effort in understanding their dynamics has been done. These studies can represent a possible avenue for the discovery of…

Results for b-quark production at hadron colliders, both current and proposed, are presented. Distributions in $p_t$ are presented for the TeVatron and SSC. Confirmation of agreement between the ${\cal O}(\alpha_S^3)$ calculations and UA1…

We study the inclusive decays of Ds+ mesons, using data collected near the Ds*+ Ds- peak production energy E_cm=4170 MeV by the CLEO-c detector. We report the inclusive yields of Ds+ decays to K^+ X, K^- X, KS0 X, pi^+ X, pi^- X, pi^0 X,…

Semileptonic decays of B mesons may be used in many different ways to probe the CKM matrix. Presented here are several recent results from the CLEO II experiment, all involving the analysis or utilization of semileptonic B decays.

I briefly review some of the results obtained using the CLEO-c detector

Using a sample of 2.59 x 10^7$ psi(2S) decays collected by the CLEO--c detector, we present results of a search for the decay chain psi(2S) -> pi^0 h_c, h_c -> n(pi^+ pi^-) pi^0, n=1,2,3. We observe no significant signals for n=1 and n=3…

Based on 2.92 fb$^{-1}$ data taken at the center-of-mass energy $\sqrt s=3.773$ GeV with the BESIII detector, we report recent results on the decay constant $f_{D^+}$, the hadronic form factors, as well as the quark mixing matrix elements…

Results on light scalar mesons in charmed particle decays studied by the CLEO Collaboration at the Cornell Electron Storage Ring are reviewed.

We review the recent experimental results on D and Ds meson leptonic decays from CLEO-c, Belle, and BABAR, which results in the decay constants f_D= (206.7 +- 8.9) MeV and f_Ds= (257.3 +- 5.3) MeV. The latter is an average obtained by the…

Using 281 pb^-1 of data collected with the CLEO-c detector, we report on first observations and new measurements of Cabibbo-suppressed decays of D mesons to 2, 3, 4, and 5 pions. Branching fractions of previously unobserved modes are…

We review some recent results on B to charmonia decays from CLEO based on 9.7 BBbar pairs collected with the CLEO detector. These include measurements of B^{0} to J\Psi K^0_s, \chi_{c1} K^0_s and J/\Psi \pi^0 branching fractions, search for…

We describe two recent results using data collected with the CLEO detector at the CESR e+e- collider at energies near the Upsilon(4S). The first is a Dalitz plot analysis of the decay D0->K0spi+pi-. We observe a rich structure including the…

We report recent measurements from CLEO of the first two moments of the photon energy spectrum for b -> s gamma decays and the hadronic recoil mass in B -> X_c l nu. These physical quantities allow one to fix non-perturbative parameters…
