In spring 2003, the B physics era ended for the CLEO experiment with a final run at the Y(5S) resonance. Over the summer the experiment and the CESR accelerator were modified to operate at lower center-of-mass energies between 3 and 5 GeV.…

Recent results from CLEO-c on measurements of absolute hadronic branching fractions of D0, D+, and Ds+ mesons are presented.

The CLEO-c research program will include studies of leptonic, semileptonic and hadronic charm decays, searches for exotic and gluonic matter, and test for physics beyond the Standard Model. In the summer of 2003 the experiment and the CESR…

We perform a full amplitude analysis of the process $e^+ e^- \rightarrow J/\psi D \bar{D}$, where $D$ refers to either $D^0$ or $D^+$. A new charmoniumlike state $X^*(3860)$ that decays to $D \bar{D}$ is observed with a significance of…

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 present an updated study of charm mixing and the relative strong phase between doubly Cabibbo-suppressed D0 --> K+pi- and Cabibbo-favored D0bar --> K+pi- decay amplitudes using 3 x 10^6 quantum-correlated D0D0bar pairs from 818 pb^-1 of…

We compare precision $e^+e^-$ to $\mu^+\mu^-$ cross section measurements by BESIII in the E_cm =3.8-4.6 GeV range, to predictions based on measured R_had data. The consistency is poor (p-value <0.012). Allowing for resonance contributions…
