We present a selection of recent results from the BESIII collaboration, including both charmonium and $D$ meson physics. We first discuss the observation of a charged, charmonium-like state, the $Z_c(3900)$. Conventional charmonium topics…
The production rates of D*+-, Ds*+-, D+-, D0 / D0bar, Ds+, and Lambda_c in Z to ccbar decays are measured using the LEP I data sample recorded by the ALEPH detector. The fractional energy spectrum of the D*+- is well described as the sum of…
The first amplitude analysis of the decay $D_s^+\to K^-K^+\pi^+\pi^0$ is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb$^{-1}$, collected with the BESIII detector at $e^+e^-$ center-of-mass energies…
We review some selected topics in the decays of heavy flavours, beauty and charm, which are of principal interest at HERA-B and HERA. The topics in $B$ physics include: an update on the quark mixing matrix and CP violating phases, issues…
Inspired by the recent measurements on the $J/{\psi}(1S)$ ${\to}$ $D_{s}{\rho}$, $D_{u}K^{\ast}$ weak decays at BESIII and the potential prospects of the charmonium at the high-luminosity heavy-flavor experiments, we study ${\psi}(1S,2S)$…
The strong-phase differences between $D^0\to K_{S/L}^0\pi^+\pi^-$ and $\bar{D}^0\to K_{S/L}^0\pi^+\pi^-$ decays are one of the most important inputs in measuring the $C\!P$ violating angle $\gamma$ via $B^- \to D K^-$ decays. They also play…
The basic physics of quantum-correlated D0, D0bar pairs produced at threshold via decays of the $\psi(3770)$ is introduced. The connection to extractions of the CKM angle $\gamma$ ($\phi_3$) from $B$ decays is emphasized throughout. Recent…
Inspired by recent BESIII's amplitude analysis on $D_s^+\to\pi^+\pi^0\pi^0$, we develop a model based on the chiral unitary approach to discribe the $D_s^+\to\pi^+\pi^0\pi^0$ decay, where $D_s^+$ decays into a $\pi^+$ and a quark-antiquark…
To write a review on charm decays is not an easy task because of the large amount (fortunately!) of experimental results in the recent years. I was forced to make a selection of topics. I am going to discuss with the eyes of an…
Semileptonic $b$-hadron decays proceed via charged-current interactions and provide powerful probes for testing the Standard Model and searching for New Physics effects. The advantages of studying such decays include the large branching…
We present preliminary results on hadronic decays of B mesons, based on data recorded at the Upsilon(4S) resonance with the BABAR detector at the PEP-II B-factory at SLAC. We measure branching fractions of many B decay modes, including…
Using a data set corresponding to an integrated luminosity of 6.32~$\rm fb^{-1}$ recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226~GeV, an amplitude analysis of the decay $D_{s}^{+} \to…
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…
I discuss the results on $D^{0}$-$\bar{D}^{0}$ mixing through hadronic as well as semi-leptonic charm decays, rare flavor-changing neutral currents in the charm sector and the lepton flavor violating $\tau$ decaying to charged lighter…
Using $e^+e^-$ annihilation data corresponding to a total integrated luminosity of 7.33 $\rm fb^{-1}$ collected at center-of-mass energies between 4.128 and 4.226~GeV with the BESIII detector, we provide the first amplitude analysis and…

Recent hadronic charm decay results from fixed-target experiments are presented. New measurements of the D0 to K-K+K-pi+ branching ratio are shown as are recent results from Dalitz plot fits to D+ to K-K+pi+, pi+pi-pi+, K-pi+pi+, K+pi-pi+…
Based on 14 million psi(2S) and 58 million J/psi events collected by the BESII detector, the leptonic decay of psi(2S) into $\tau^+\tau^-$, psi(2S) multi-body decays, chi_cJ decays, and J/psi hadronic decays are studied, and the branching…
In this article, we assign the $D_{s3}^*(2860)$ to be a D-wave $c\bar{s}$ meson, study the hadronic coupling constants $G_{D_{s3}^*(2860)DK}$ and $G_{D_{s3}^*(2860)D^*K}$ with the three-point QCD sum rules, and calculate the partial decay…
