STAR QA Board

[林挺 <tinglin@sdu.edu.cn>]

Hi all:

A brief minutes for today's meeting:

https://drupal.star.bnl.gov/STAR/event/2021/10/22/qa-board-meeting

1. Centrality:

We have good agreement for centrality QA: 1. No pile-up cuts (like TOFMatch cut); 2. Lower nhits cut to 10; 3. Power pT cuts to 60 MeV. So the list of cuts and variables:

Cut used: 

145 #MAX_AbsVz [cm] this is max |Vz| 
145 #MAX_Vz [cm] this is max |Vz| 
-145 #MIN_Vz [cm] this is max |Vz| 
2 #MAX_Vr [cm]

10 #MAX_nHitsFit
3 #MAX_gDCA [cm] 
0.06 #MIN_pT [GeV] 
2 #MAX_pT [GeV] 

Variables:
<RefMult> 
<eta>

<phi> 

<DCA>
dEdx

2. LF group:

Use the same cut as centrality, additional variables: 

Event level: Mean Number of primary tracks, Mean bToFMult (number of btof hits)
Primary Track: Mean pT, Mean bToF 1/beta.

3. CF group:

same as LF group, with additional variables:

Mean of sDCAxy, Mean of sDCAxy RMS, <tofmatched>, <Bbc> , <Zdc> , <Nhitsfit>

4. FCV group:
additional variables:

Q1 and Q2 (x,y TPC EPD BBC ZDC), EPD east hits, EPD west hits.

5. HF group:

additional variables:

VPD hits east, VPD hits west, bTofYLocal, bTofZLocal, eTof Delta X, eTof Delta Y, eTof Hits, eTof 1/Beta, number of MTD hits, number of MTD hits matched with TPC tracks

6. Jet Corr:

additional variables:

EMC cuts: average hit energy, number of bad towers from database; 

Jet QA: jet pt, number of jets, eta, phi. Maybe should working with SpinGroup for pp runs in the next few years.

QA for centrality should start as soon as possible, check the setup with people from centrality group (Grigory). While for those that is specific for different working groups, will need to work with different groups to make things working.

Please let me know if something is missing. Best,

Ting

Hi all:

We will have QA board meeting tomorrow at noon. The main agenda is discussing the list of variables that is needed for the BES-II data QA. If you have slides to show, feel free to add talks in the page below:
