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¥…
