Precision measurements of the D -> pi e+ nu form factor could shed new light on the persistent difference between inclusive and exclusive measurements of Vub. We report the measurement of the partial branching fraction of D -> pi e+ nu in bins of the four-momentum transfer squared of the D to pi system using 347.2 /fb of integrated luminosity of the BaBar data. The D -> pi form factor is...

Following the intriguing hints of deviations from the Standard Model in rare B meson decays, searches for rare and forbidden decays of charm hadrons become a hot topic again. We present recent results on penguin D→μμhh' and lepton-flavour violating D→eμ decays.
These results are presented on behalf of the LHCb collaboration.

We present a study of c → ull transitions.
In the Standard Model these semileptonic charm decays are induced via Flavor Changing Neutral Currents and, thus are rare.
This opens possibilities for potential Beyond Standard Model physics searches.
We estimate phenomenological observables within the SM and effects due to BSM physics.

Based on the sample taken at sqrt(s) = 3.773 GeV with 2.92/pb, which corresponds to the largest sample of e+e- -> psi(3770) in the world to date, we present our results of searches for flavor changing neutral curent and lepton number violation decays of the charged D meson in the final states of; D+ -> K+ e+ -, K- e+ e+, pi+ e+ e-, pi-e+ e+, as well as other searches such as for D0 -> gamma gamma.

Based on 2.92 fb$^{-1}$ of $e^+e^-$ collision data taken at $\sqrt{s}$ = 3.773 GeV with the BESIII detector at BEPCII, we present preliminary results from the analysis of the decay $D^0 \to K_S^0 K^+ K^-$. We measure the branching fraction and investigate the rich substructure in the final state by performing a Dalitz plot analysis.

We report the measurement of the D0-D0bar mixing parameter, y_{CP} based on the sample taken at the DDbar mass threshold. Based on the events where we reconstruct one D decays to CP eigenstates while the other D decays semi-leptonially, we obtain y_{CP} = (-2.0+-1.3+-0.7)%. We also present results for model independent measurement of the strong phase difference between D0 and D0bar -> K0 pi+...

I will show an exclusive approach on calculating the DDbar mixing parameters y and x. We will sum up the contributions from the hadronic decays, based on the factorization-assisted topological-amplitude approach in which most SU(3) breaking effects are involved.

LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for indirect CP violation in charm, and to measure D0 mixing parameters. New measurements from several decay modes are presented.

The study of T-odd observables using four-body hadronic final states of charm meson decays provides complementary insight to measuring CP asymmetries via decay rate asymmetries. New results based on the full LHCb dataset are presented.
