Search for a pentaquark state decaying into $p J / I ¨ $ in $I^¥ (1, 2 S)$ inclusive decays at Belle

Belle Collaboration, X. Dong, S. M. Zou +162

Using the data samples of 102 million $I^¥ (1 S)$ and 158 million $I^¥ (2 S)$ events collected by the Belle detector, we search for a pentaquark state in the $p J / I ¨ $ final state from $Î¥…

Search for lepton-flavor-violating tau decays to $ℓ I^\pm$ at Belle

Belle Collaboration, K. Uno, K. Hayasaka +123

We report a search for the lepton-flavor-violating decays $I ¨ ^{\pm} \to ℓ^{\pm} I^\pm$ ~( $ℓ = e, I^¼$ ), where $I^\pm$ is an undetected spin-0 particle, such as an axion-like particle using…

Angular analysis of $B \to K^{*} e^{+} e^{-}$ in the low- $q^{2}$ region with new electron identification at Belle

Belle Collaboration, D. Ferlewicz, P. Urquijo +167

We perform an angular analysis of the $B \to K^{*} e^{+} e^{-}$ decay for the dielectron mass squared, $q^{2}$ , range of $0.0008$ to $1.1200 GeV^{2} / c^{4}$ using the full Belle data se…

Evidence of $h_{b} (2P) \to I^¥ (1S) I^\cdot$ decay and search for $h_{b} (1P,2P) \to I^¥ (1S) I ¨ ^{0}$ with the Belle detector

Belle Collaboration, E. Kovalenko, I. Adachi +164

We report the first evidence for the $h_{b} (2P) \to I^¥ (1S) I^\cdot$ transition with a significance of $3.5$ standard deviations. The decay branching fraction is measured to…

Search for Two-Body $B$ Meson Decays to $I^^{0}$ and $I^c ◯_{c}^{(*) 0}$

Belle Collaboration, V. Savinov, I. Adachi +146

We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral $B$ mesons to $I^^{0}$ and $I^c ◯_{c}^{(*) 0}$ using 711~${\rm fb^…
