Description

1. Operator conversion note is prepared already, please have a look at the conversion relationship between the new energy physics cutoff scale , operator Wilson coefficient and effective vertex form factors.

2. Tencent Meeting Room : https://meeting.tencent.com/dm/kE833HzqpILL

会议号：638-6254-8241

Minutes :

1. Use nominal Sherpa2.2.11 (SM Zgamma sample, no EFT contributions) to check the binning, if possible, maybe can use data, but right now, I think data is blinded

2. Move to Z+Jets background estimation, get some results as soon as possible

3. Try to understand the fitting results : why best fit value is not exactly 0

4. Consider to add systematics, in principle, we will stay same with differential measurement ?

Also, considering 0-jet selection, should we add jet systematics ?

There are minutes attached to this event. Show them.
