Motivated by the possible large direct CP asymmetry of \bar{B}^0_d \to D^+ D^- decay measured by Belle collaboration, we investigate double charm B_{u,d} and B_s decays in the minimal supersymmetric standard model with R-parity violation.…
We study radiative charm decays $D \to P_1 P_2 \gamma$, $P_{1,2}=\pi,K$ in QCD factorization at leading order and within heavy hadron chiral perturbation theory. Branching ratios including resonance contributions are around $\sim 10^{-3}$…
In this proceeding, results of searches for CP violation in charm decays using the full BABAR dataset are discussed. The parameter $A_{CP}$ in the decay $D^\pm\to\KS\pi^\pm$ is determined to be $(-0.39 \pm 0.13 \pm 0.10)%$. Meaurements of…
We exploit the quantum coherence between pair-produced D0 and D0bar in psi(3770) decays to study charm mixing and to make a first measurement of the relative strong phase \delta between D0 -> K+pi- and D0bar -> K+pi-. Using 281 pb^-1 of…
The decay $D\to K^-\pi^+$ is studied in a sample of quantum-correlated $D\bar{D}$ pairs, based on a data set corresponding to an integrated luminosity of 2.93\,fb$^{-1}$ collected at the $\psi(3770)$ resonance by the BESIII experiment. The…
The decays B -> D^{**} pi, where D^{**} is a narrow p-wave charm resonance, are investigated in the context of a generalized factorization hypothesis, including the leading nonfactorizable corrections. The decay rates for these processes…
The measurement of $\sin {2\beta}$ from $B_d \to J/\psi K_s$ does not resolve the discrete ambiguities in the angle $\beta$. A measurement of $\cos {2\beta}$ is therefore desirable.This talk is about measuring the CKM angle $\beta(\phi_1)$…
We present a summary of new experimental results on the status of the charm spectroscopy using inclusive approaches and Dalitz plot analyses of $B$ and $B_s$ decays. We also report on a new determination of the $X(3872)$ quantum numbers.
We present recent results of B and charm decays from the BaBar experiment. These results include searches for rare or forbidden charm decays, measurements of $|V_{ub}|$ from inclusive ${\bar B} \rightarrow X_u l {\bar \nu} $ decays,…
We report on the charm physics potential at BES-III at BEPC-II which will make significant contribution to quark flavor physics this decade. The charm physics program will include studies of leptonic, semileptonic and hadronic charm decays,…
We identify two Cabibbo suppressed $D^+$ decay modes with anomalously high branching ratios which are not simply explained by any model. All standard model diagrams that can contribute to these decays are related by symmetries to diagrams…
Quantum correlations in $\psi(3770) \to D^0\bar{D}^0$ provide unique access to information about strong phase differences. Precision determination of the CKM phase $\gamma/\phi_3$ via $B \to D K$ decays depends upon constraints on charm…
The BESIII experiment has collected 2.6 billion $\psi(3686)$ events, 10 billion events, 20 $fb^{-1}$ of $D$ meson pairs at 3.773 GeV, and 7.33 $fb^{-1}$ of $D_sD_s^*$ events from 4.128 to 4.226 GeV. These huge data samples allow us to…

A study of charm mixing and CP violation in $D^0\to K^\pm\pi^\mp\pi^\pm\pi^\mp$ decays is performed using data collected by the LHCb experiment in proton-proton collisions from 2015 to 2018, corresponding to an integrated luminosity of…
We describe a newly formulated approach to account for charm production and decay in Statistical Hadronization approach. Considering Pb--Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV at LHC we show that charm hadron decays can be a…
Motivated by the very important discovery of CP violation in charm-decays for the first time, by the LHCb collaboration, the role of nearby resonances such as the scalar $f_0(1710)$ in accounting for the observed CP is discussed. It is…
Very recently, the LHCb Collaboration observed the $CP$ violation (CPV) in the charm sector for the first time, with $\Delta A_{CP}^{\rm dir}\equiv A_{CP}(D^0\to K^+K^-)-A_{CP}(D^0\to \pi^+\pi^-)=(-1.54\pm0.29)\times10^{-3}$. This result is…
