- TPC - Gene reported slewing correction for clusters is in DB. T0 should be in DB at the end of the week. Then we can ask for re-production of one fill to see if tracking efficiency improved at Z~0
- PPV - status of evaluation of SL09b production - no report
- Vernier scan - Ross
- formula computing BBC xsection seems to be complete now. For a low lumi fill in pp500 the computed BBC xsection is 26mb - close to the value know for pp200
- Q: what do we expect for BBC xsection at 500 GeV - answer is unknown
- the linear formula can't be applied for regular fills when BBC is saturated, Hal suggested using more advanced approach counting bXings w/o rate, using zero of Poisson distribution. LINK SHOULD BE HERE
- BHT3 x-section : results of fit with noisy patches removed Conclusion: background reduces but not vanishes. Comparison for other vernier scan will be made, estimation of error in determination of xSection due to non vanishing background will be made
- BTOW calibration
- relative -Joe - link , is completed. Write-up was sent to emc2-hn for comments.
- absolute -Matt, will be performed shortly using Joe's relative gains.
Wiki Markup Understanding QCD e+/e\- ratio at ET \[15,20\] GeV - Scott.- Plan:
- use
- Pythia
- events
- and
- simplified
- W-algo
- to
- determine
- the
- ratio
- of
- high
- pT
- particles
- with
- positive/negative
- charge.
- Manpower:
- not
- assigned.
- Status of W analysis:
- Joe detailed presentation of alternative W-algo, run 9 data & M-C - link. Results are consistent with Jan's analysis. 2 independent algos leading to similar output improve confidence in the result.
- Jan's ver 4.2 : bug fix, upgrade, answers to questions after last week spin PWG presentation , slides
- Justin : using ETOW in W-algo improves S/B in ET~20 GeV region, allows background estimation for di-jets escaping through not existing East endcap.
- Layout of paper 1: Draft: Files: Bernd
Decisions:- Bernd will oversee the latex files, complete version will be posted in spin/protected/ area at THIS LOCATION
- Assigned chapters: Intro+Rhic RHIC : Bernd; STAR : Scott; Lumi : Ross; Trigger : Jan
- We hope to have them written by next week.
- CNI polarization of protons during 500 GeV run (Data files: ): Yellow Fill dependence: and Blue Fill dependence: - Bernd?
- Announcements
- Hal finished run QA for fills: 10403, 10404, 10407, 10412.
