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…
