We report the first observation of radiative decay B^0 -> \phi K^0 \gamma using a data sample of 772x10^6 BBar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe a signal…

We present a measurement of the branching fractions for the Cabibbo-favored radiative decay, $D^{0} \to {\bar K}^{*0} \gamma$, and the Cabibbo-suppressed radiative decay, $D^{0} \to \phi \gamma$. These measurements are based on a data…

The radiative decay $B \to \phi K \gamma$ is observed for the first time. The branching fraction for the charged $B^- \to \phi K^- \gamma$ decay mode is measured to be ${\cal B}(B^- \to \phi K^- \gamma) = (3.4 \pm 0.9 \pm 0.4) \times…

We report the first observation of the radiative charm decay $D^0 \to \rho^0 \gamma$ and the first search for $CP$ violation in decays $D^0 \to \rho^0 \gamma$, $\phi\gamma$, and $\overline{K}{}^{*0} \gamma$, using a data sample of 943…

We observe the radiative decay $D^{*}_{s0}(2317)^{+} \to D_{s}^{*+} \gamma$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the continuum $e^+ e^- \to c\bar{c}$ process with the combined…

We report the first observation of color-suppressed $\overline{B}^0\to D^0 \pi^0$ and $D^{(*)0} \omega$ decays and evidence of $\overline{B}^0 \to D^{*0} \pi^0$ and $D^{(*)0} \eta$. The branching fractions are found to be ${\cal B}…

Using a data sample corresponding to an integrated luminosity of 2.93 fb$^{-1}$ collected at a center-of-mass energy $\sqrt{s}=3.773$ GeV by the BESIII detector, the decay $D^0 \to\omega\phi$ is observed for the first time. The branching…

We report the recent results of charmed baryon decays, based on the data collected by the Belle experiment at the KEKB collider. This includes the observation of the doubly Cabibbo-suppressed decay $\Lambda_c^+\to\pi^-K^+p$, search for the…

Using the large data sample accumulated by the Belle experiment at KEKB asymmetry energy $e^+e^-$ Collider, we report the preliminary measurements of the branching fractions of the radiative decays $D^0 \rightarrow V\gamma$, where $V$ =…

We present a measurement of the branching fraction for the Cabibbo- and color-suppressed $B^0 \to \chi_{c1}\pi^0$ decay based on a data sample of $657\times 10^6$ $B\bar B$ events collected at the $\Upsilon(4S)$ resonance with the Belle…

In this proceeding, we discuss recent results on exclusive radiative B meson decays from the Belle Collaboration. These decays are sensitive to right-handed currents from New Physics. In particular, we measure time-dependent CP violation…

We present improved measurements of the branching fractions of the color-suppressed decays $\bar{B}^0 \to D^{(*)0} h^{0}$ where $h^{0}$ represents a light neutral meson $\pi^{0}$, $\eta$ or $\omega$. The measurements are based on a data…

Rare radiative decay $\phi\to\eta\pi^0\gamma$ was studied with SND detector at {VEPP-2M} electron-positron collider and its branching ratio was measured: $B(\phi\to\eta\pi^0\gamma)=(0.88\pm0.14\pm0.09)\cdot 10^{-4}$. Significant…
