During the last few years there has been a renaissance in charm and charmonium spectroscopy with higher precision measurements at the $\psi^{'}$ and $\psi(3770)$ coming from BESII and CLEOc and many new discoveries coming from B-factories.…
Implications of recent CLEO measurements of hadronic charmless B decays are discussed.

The combined symmetry of charge conjugation and parity ($C\!P$) is tested in the hadronic transition $\psi(3686)\to\pi^+\pi^{-}J/\psi$, utilizing a dataset of 2.7 billion $\psi(3686)$ events collected by the BESIII detector at the BEPCII…

The inclusive charm hadron semileptonic branching fractions B(c to e) and B(c to mu) in Z to ccbar events have been determined using 4.4 million hadronic Z decays collected with the OPAL detector at LEP. A charm-enriched sample is obtained…
The latest results on chi_cJ(1P) decays from BESIII and CLEO-c are reviewed and compared to theoretical predictions. The experimental results use the final samples of chi_cJ(1P) decays from CLEO-c, obtained from 26 million psi(2S) decays,…
I discuss the most recently discovered open charm mesons, both with and without strangeness. By exploiting the heavy quark limit, strong decay widths of such mesons are computed. Comparison between theoretical predictions and experimental…

Using 13.7 fb^{-1} of data recorded by the CLEO detector at CESR, we investigate the spectrum of charmed baryons which decay into Lambda_c^+ pi^- pi^+ and are more massive than the Lambda_{c1} baryons. We find evidence for two new states:…
We modify the mesonic wavefunction by using a short distance scale r0 in analogy with Hydrogen atom and estimate the values of masses and decay constants of the open flavour charm mesons D, Ds and Bc within the framework of a QCD Potential…
The production of charm quarks is studied in deep-inelastic electron-photon scattering using data recorded by the OPAL detector at LEP at normal e+e- centre-of-mass energies from 183 to 209 GeV. The charm quarks have been identified by full…
This paper gives a short summary of some of the aspects of charmonium which can be addressed at BES and CLEO-c and other $e^+e^-$ facilities. These topics include the spectroscopy of charmonium states, radiative transitions, $e^+e^-$…
We review how quark models are able to describe the phenomenology of the charm meson sector. The spectroscopy and decays of charmonium and open charm mesons are described in a particular quark model and compared with the data and the…
In this talk, I review the recent experimental results on charmonium spectroscopy from BESIII, Belle, BaBar and CLEOc. Below the open-charm threshold, the masses and widths of spin-singlet states eta_c, eta_c(2S), h_c are measured with high…

In the light of recent experimental data from the CLEO Collaboration we study, the decays of B mesons to a pair of pseudoscalar (P) mesons, and a vector (V) meson and a pseudoscalar meson, in the framework of factorization. In order to…
The huge data sample accumulated at the KEKB storage ring allows for dedicated analyses in charm spectroscopy. A new, narrow resonance with a mass of 3.872\GeV was found in decays of $B$ mesons. Its properties remain unexplained. Results on…
The "BTeV/C0" experiment at Fermilab could reconstruct >10^9 charm decays, four orders of magnitude beyond the largest extant sample. The experiment is likely to run during Tevatron Run II (ca. 2000--2005). In addition to "programmatic"…
Charm production is studied in deep-inelastic electron-photon scattering using OPAL data at e+e- centre-of-mass energies from 183 to 209 GeV. Charm quarks are identified by exclusive reconstruction of D* mesons. The cross-section of D*…
