1) Data - Kunsu
Slide 2, BHT2 – 26M, BHT3 – 10M
Slide 3, PhE from data, actually include contribution from Dalitz and photon conversion
Slide 4,
-       error bars not plotted, Kunsu commented it is typically large, around 0.7-0.8, this may indicate we may not have the sensitivity to the c/b electrons
-       suggest to
1)   make the fit within 0.02 cm region
2)   what if we don’t use c,b->e component, does the two (Dalitz+PhE) fit the data points? Compare the fit quality chi2 for two component fit vs. four component fit.

PhE conversion reconstruction
Need to check in data whether the DCA distributions between the following two are the same or not
a)    single conversion electrons with tagged electron selection cut
b) out of these conversion electrons, those get reconstructed with the same reconstruction algorithm as in data

==>QM poster plan<==
Raw DCA distribution from data, photonic electron reconstruction
MC – c,b->e DCA distribution, Dalitz DCA
Sensitivity estimation on eb/(ec+eb) ratio - TBD

2) Simulation Xiaozhi
D->e, there is a question about D+/D0 contribution, Xiaozhi will check
Slide 5, Suggest to separate conversion/Dalitz from data using reconstruction radius and mass cut. Then compare with MC separately.
To merge the two components from MC, one would need a good understanding on the relative contribution between conversion and Dalitz which means good understanding on the absolute material.
