We review status of $R$ measurement and QCD studies at low energy range, discuss prospects for a super $\tau-$charm factory in $2-7$ GeV. With a high-luminosity $e^+e^-$ collider, statistics are no longer problem for $R$ measurement and a…
The proposed experimental program (CLEO-c) for a charm factory based on a modification of the Cornell Electron Storage Ring is summarized. The prospects for R measurements over the range 3 GeV to 7 GeV are examined in detail. Adapted from…
I review the sensitivities achieved by and projected for fixed-target charm experiments in CP violation, flavor-changing neutral-current and lepton-number-violating decays, and mixing, and I describe the Charm2000 experiment intended to run…
Charm physics has been studied with many dedicated accelerators and experiments. In these proceedings, we review the status and the selected results of the current operating BEPCII/BESIII experiment. We also discuss the BESIII data taking…
We present new results on charm hadron decays from the CLEO II experiment. The D*+ width is measured for the first time, Gamma(D*+) = 96 +- 4 +- 22 keV. The semileptonic decay branching fractions are determined to be B(D+ --> Kbar*0 e+…
We review current experimental results on charm mixing and CP violation. We survey experimental techniques, including time-dependent, time-independent, and quantum-correlated measurements. We review techniques that use a slow pion tag from…
Recent CLEO-c results on open and closed charm physics at center of mass of 3773 MeV (psi(3770) resonance), 4170 MeV and 3686 MeV (psi(2s) peak) are reviewed. Measurements of absolute hadronic branching ratios of D0, D+ and Ds mesons as…
Large production of the $\ccbar$ pairs and high integrated luminosity make the PEPII B-Factory, an excellent place for studying the charm hadrons. In this paper, we present a few of the most recent results from the BaBar collaboration in…
We consider the prospect of using the charm system as a laboratory for probing new physics. The theoretical expectations for rare charm meson decays, $D^0-bar D^0$ mixing, and charm quark asymmetries in $Z$ decays are examined in the…
$\tau$ decays provide a powerful tool to test the structure of the weak currents and the universality of their couplings to the $W$ boson. The constraints implied by present data and the possible improvements at the $\tau$-charm Factory are…
Although CP violation is predicted to be small in the Standard Model, there exists a continuing theoretical interest within the charm sector due to enhancements of CPV through new physics processes. We present an overview of the…
Main parameters of the linac-ring type charm-tau factory are discussed. Different sets of parameters for an electron linac and a positron ring have been considered. It is shown that L=10^33 cm-2 s-1 and even more can be achieved. The…
A personal overview of the current status of physics results from LEP using b-hadrons is presented. Emphasis is placed on those areas where analyses are not yet finalised and there remains significant activity. Results are presented in the…
Using an inclusive method, BR(b -> D\bar{D}X) has been measured in hadronic Z^0 decays with the OPAL detector at LEP. The impact parameter significance of tracks opposite tagged b-jets is used to differentiate b -> D\bar{D}X decays from…
This article summarises measurements of time-dependent CP asymmetries in decays of neutral B mesons to charm final states using data collected by the BaBar detector at the PEP-II asymmetric-energy B-factory. All results are preliminary…
For a long time the significance of charm has been overlooked as an important component of the heavy flavour programme. In recent years the balance has been redressed, and charm studies are quite rightly receiving much more attention. This…
We report on the physics potential of a proposed conversion of the CESR machine and the CLEO detector to a charm and QCD factory: CLEO-c and CESR-c that will make crucial contributions to flavor physics in this decade and offers our best…
Searches for CP violation in the charm sector from the E791, FOCUS, CLEO, BABAR and BELLE experiments are presented. Most analyses consider CP violation in two-body or quasi-two-body decays. Preliminary results from CLEO and FOCUS using…
We begin with giving some motivation for the study of charm semileptonic and fully leptonic decays. We turn next to a discussion of semileptonic absolution branching fraction results form CLEO-c. Two exciting high statistics results on…
I review the current status of measurements involving semi-tauonic $B$ meson decay at the $B$-factories. I briefly discuss the experimental methods and highlight the importance of background contributions especially from poorly understood…
