This is the first meeting. We discussed how to collaborate on the NPE analysis and agreed that our goal is to separate B/D decayed electrons based on DCA, which needs both extensive data and simulation studies. It was agreed that Kunsu can focus on the data part while Xiaozhi on simulation. Kunsu presented slides on first trial of producing NPE trees. 

Wei pointed out that NPE results from p+p run12 is important as it has smaller uncertainties than published and Run09, and should be finalized as well while working on Run14.
