Search for a pentaquark state decaying into $pJ/\psi$ in ${\rm Y}(1,2S)$ inclusive decays at Belle

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

Using the data samples of 102 million ${\rm Y}(1S)$ and 158 million ${\rm Y}(2S)$ events collected by the Belle detector, we search for a pentaquark state in the $pJ/\psi$ final state from $Υ(1,2…
