The processes $D^0\to K^0 K^-\pi^+$ and $D^0\to\ok K^+\pi^-$ involve intermediate vector resonances whose amplitudes and phases are related to each other via flavor SU(3) symmetry. A closer look at Dalitz plots for these two processes is…
Using 281 pb^{-1} of data recorded by the CLEO-c detector in e^+e^- collisions at the psi(3770), corresponding to 0.78 million D^+D^- pairs, we investigate the substructure of the decay D^+ to pi^- pi^+ pi^+ using the Dalitz plot technique.…
We study the processes $\gamma \gamma \to K^+ K^- \eta$ and $\gamma \gamma \to K^+ K^- \pi^0$ using a data sample of 519 $fb^{-1}$ recorded with the BaBar detector operating at the SLAC PEP-II asymmetric-energy $e^+ e^-$ collider at…
We perform a coupled-channel analysis of pseudodata for the D+-> K-pi+pi+ Dalitz plot. The pseudodata are generated from the isobar model of the E791 Collaboration, and are reasonably realistic. We demonstrate that it is feasible to analyze…
A quasi two-body QCD factorization is used to study the D0 --> K0S pi+ pi decays. The presently available high-statistics Dalitz plot data of this process measured by the Belle and BABAR Collaborations are analyzed together with the tau-…
We report on the Dalitz plot analyses of B^- \to D^+ \pi^-\pi^-, B^+ \to \pi^+ \pi^- \pi^+ and D^+_s \to \pi^+ \pi^- \pi^+. The Dalitz plot method and the most recent BABAR results are discussed.
The amplitude of the Dalitz decay pi0 -> e+ e gamma is studied and its model-independent properties are discussed in detail. A calculation of radiative corrections is performed within the framework of two-flavour chiral perturbation theory,…
As first observed by the NA48/2 experiment at the CERN SPS, the $\p0p0$ invariant mass (M00) distribution from $\kcnn$ decay shows a cusp-like anomaly at M00=2m+, where m+ is the charged pion mass. An analysis to extract the pi pi…
The resonant substructures of $B^0 \to \overline{D}^0 \pi^+\pi^-$ decays are studied with the Dalitz plot technique. In this study a data sample corresponding to an integrated luminosity of 3.0 fb$^{-1}$ of $pp$ collisions collected by the…
We analyse the consequences of the usual assumption of a constant function to fit non-resonant decays from experimental Dalitz plot describing charmed meson decays. We first show, using the $D^+\to \bar{K}^0\pi^+\pi^0$ decay channel as an…
Recently B-factories have published new results on the $B \to K \eta \gamma$ decays being inspired by the theoretical suggestion to search for new physics in $B \to P_1 P_2 \gamma$ decays. Using heavy meson chiral perturbation theory we…
We present a Dalitz plot analysis of B- --> D+ pi- pi- decays, based on a sample of about 383 million Y(4S) --> BBbar decays collected by the BaBar detector at the PEP-II asymmetric-energy B Factory at SLAC. The analysis has been published…
Using 281/pb of data recorded by the CLEO-c detector observing e+e- collisions at the psi(3770), corresponding to 1.8 million D Dbar pairs, the substructure of the decay D+ to pi+ pi- pi+ is investigated using the Dalitz plot technique. The…
We present recent results on scalar light mesons based on Dalitz plot analyses of charm decays from Fermilab experiment E791. Low mass scalar mesons are found to have large contributions to the decays studied, D^+\to K^-\pi^+\pi^+ and D^+,…
We present the results of the first Dalitz plot analysis of the decay $D^{0}\to K^{-}\pi^{+}\eta$. The analysis is performed on a data set corresponding to an integrated luminosity of 953 $\rm{fb}^{-1}$ collected by the Belle detector at…
We present several recent analyses of Dalitz plots from the CLEO-c experiment, including published and preliminary analyses of D+ to pi- pi+ pi+, D+ to K- pi+ pi+, and D0 to K0_{S,L} pi+ pi- decays. More information on these analyses can be…
We report a Dalitz-plot analysis of the charmless hadronic decays of charged B mesons to the final state K+/- pi-/+ pi+/-. Using a sample of 226.0 +/- 2.5 million BBbar pairs collected by the BaBar detector, we measure the magnitudes and…
We study the processes $\gamma \gamma \to \eta_c \to \eta' K^+ K^-$, $\eta' \pi^+ \pi^-$, and $\eta \pi^+ \pi^-$ using a data sample of 519 $fb^{-1}$ recorded with the BaBar detector operating at the SLAC PEP-II asymmetric-energy $e^+e^-$…
We perform an analysis of the $D^+ \to K^0_S \pi^+ \pi^0$ Dalitz plot using a data set of 2.92 fb$^{-1}$ of $e^+e^-$ collisions at the $\psi(3770)$ mass accumulated by the BESIII Experiment, in which 166694 candidate events are selected…
Dalitz analyses in charm give access to both magnitudes and phases of the charm decay amplitudes. They play a significant role in charm-mixing measurements, in the measurement of the CP-violating phase gamma in B decays to charm, and in the…
