20240923 CEPC physics performance for Ref-TDR 例会纪要
参会人员:陈明水,李刚,陈缮真,Reda,燕萍,泽炳, 陈晔,李嘉荣,曼奇,凯栗,辰光,单连友,梁诗怡,马晓天, 张鹏
线上: 徐达,梁志均,庄胥爱,李衡讷,王锦,Leyan Li,  孙小虎,Yuchen Cai,朱昊,Hancen Lu,
 
	- general information
	
		- List of tasks - encourage everyone to continue volunteering 
 
		- CEPCSW tutorial sessions organized by software group on 12-13, Sep.
		
		
 
		- review of budget request of the Henan funding done yesterday,will need to update the proposal with more detailed information (10x more) before the national holiday
 
	
	 
 
	- Chenguang: already look into the tracking/vertex in CEPCSW (package/LCFIPlus migrated from CEPCsoft and compiled)  
	
		- Gang/Manqi suggest taking PFO output 
 
	
	 
 
	- Kaili updates on the Fast simulation of the CEPC detector with Delphes
	
		- plan mainly for large background samples 
 
		- one can start preparation of analyses framework/code based Delphes samples 
 
		- all the configuration/parameters can be quickly adapted to latest detector design
 
		- should be validated in order to be included in the TDR
 
		- also provide configurations for Ideal/dream case 
		
			- any difference between the design goal and actual design should be understood and explained, future prospects should be provided
 
		
		 
		- need versioning of the samples 
 
	
	 
 
	- Kaili updates on the estimates of the full simulation sample 
	
		- 1.4 M events quoted for priority samples for performance study, currently several minutes per event -> will need 6 days with 1000 CPU
 
		- proposed 360 GeV processes: ZvvHbb and WW-fusion->vvHbb, should consider interference  
 
	
	 
	- Before full simulation production, gen level information/generator should be validated
	
		- number of gen events could be larger
 
		- need to define a list of plots/variables for validation 
 
	
	 
 
	- Vcb -  paper based on CDR is nearly published, can be moved to TDR quickly  -  need someone to take it from Liang Hao and Lin Feng. 
 
 
	- Analyzers are preparing (or will start soon) analysis framework
 
	- need to define a list of preformance plots -> for validation,  cross check, TDR needed,  and easier distribution of the tasks
	
		- e.g. tracking performance as an example,  as in a previous internal note (attached in the indico)
 
		- will be collected in the following Excel sheet https://docs.qq.com/sheet/DT2V5VVN4cXRHeGZY?tab=x6jl4c&_t=1727084143791
 
	
	 
	- Provide a couple analyses examples: (may start from CDR code)  
 
 
             
            
                
                    There are minutes attached to this event.
                    
Show them.
