1) Photonic Electronic in Run14 data - Shenghui
correct a bug in Like-sign background yield, it was scaled by 0.5 before. Difference between 2 and 3, pT>0.2 for Slide 2, pT>0.8 for Slide 3. 

slide 3: there is a vertical structure in conversion radius 2D plot at x~0 y<0. Is there due to conversion from wires attached to beam pipe? Bingchu said Run11 shows such a structure :

slide 3: 1D like-sign plot at R~8cm. Shenghui: plot ndEdx_electron for unlike-sign and like-sign partner vs partner pT with 7.5<radius<9 cm.  Xiaozhi: plot like-sign conversion radius in simulation

apply pt-dependent invmass cut to select photonic electron pair

2) simulation - Xiaozhi

3) eK pairs - Jie
find out where electrons with large DCA come from;
separate B and D signals; add Bs, 
will use dca12 to find closest pairs and find the first set of selection cuts to see if we can achieve reasonable S/B.

4) Kunsu will stay at LBNL for the next year. He will focus on gamma tomography in the next few weeks.
