Abstract
The Belle II experiment has accumulated data corresponding to 213 fb-1 of integrated luminosity in the past two years. Belle II plans to accumulate 50 ab-1, which are expected to bring a large impact to the field of hadron spectroscopy. We present here the analysis of B ? KJ/?p+p- and B ? K?(2S) decays using 62.8 fb-1 at Belle II. We find evidence of X(3872) ? J/?p+p- decays with a signal yield of 14.4 ± 4.6 and a statistical significance of 4.6 s. We also present preliminary results of e+e- ? p+p-J/? via ISR using 37.8 fb-1 © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0)
