Search for the radiative penguin decays B0→KS0KS0γ in the Belle experiment

H. B. Jeon, K. H. Kang, H. Park, I. Adachi et autres

We report results from the first search for the rare penguin-dominated decay mode ${B}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}\ensuremath{\gamma}$, which can result from the production of tensor mesons $f(1270)$ and ${f}^{\ensuremath{'}}(1525)$ in association with a photon. The search uses the full data sample of $772\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }B\overline{B}$ …

First test of lepton flavor universality in the charmed baryon decays Ωc0→Ω−ℓ+νℓ using data of the Belle experiment

Y. B. Li, C. P. Shen, I. Adachi, H. Aihara et autres

We present the first observation of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{\ensuremath{\nu}}_{\ensuremath{\mu}}$ decay and present measurements of the branching fraction ratios of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\ell}}^{+}{\ensuremath{\nu}}_{\ensuremath{\ell}}$ decays compared to the reference mode ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, ($\ensuremath{\ell}=e$ or $\ensuremath{\mu}$). This analysis is based on $89.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, $711\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, and …

Search for $B^{0} \to K_S^{0}K_S^{0}\gamma$ decays at Belle

Belle II Collaboration, H. B. Jeon, K. H. Kang, H. Park et autres

We report the first search for the penguin-dominated process $B^0 \rightarrow K_S^0 K_S^0 \gamma$ using the full data sample of $772\times 10^6$$B\bar{B}$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We do not observe any statistically significant …
