10:05 → 10:15 Status

Speaker: Kang Yu (TDLI, SJTU)

Sorry, I don't have any update. I just took 1 shift and finished my homework during the holiday.

ZZy_5.6.pptx

ZZy

• Set up script-based job submission for downloading Run 3 MC samples, and downloaded a small subset of mc23 Zy DAOD_PHYS samples for local framework tests.
• Tested the H2Zy framework as a possible Run 3 DAOD_PHYS-compatible alternative to the legacy HGamGamStar/DAOD_HIGG1D2 workflow. The local workflow can run and produce output, but no events pass the current selection, so further checks on sample compatibility, trigger, object selection and so on.
• Started looking into Grid-based production as the more scalable direction, since downloading full DAOD datasets to personal storage is not practical.

Plans

• Discuss using grid for larger statistics and validating/adapting the current framework selections for Run 3.

10:45 → 10:55 Status

Speaker: Bai-Hong Zhou (TDLI, SJTU)

Today's focus: 

[ssWW]:

• Fixed the errors in grid submission with the latest easyjet framework;
• Launched a new ntuple production process (with fjet information included);

[Hyy*]:

• Check the validation results: quickFit has the same results with quickstate (expected);

[DarkSHINE]:

• Fixed the typo in Section 3.3 of our CDR;
• Uploaded my comments in Haydar's document;

---

Plans: 

 

[ssWW]:

• Wait for the finish of the ntuples production;
• Make a new MR truth information and truth selection implemented;
• Train the ParT with the latest ntuples;

 

[Zbbj Calibration]:

• Push all my fitting framework related codes to the main branch;

11:15 → 11:25 Status

Speaker: Haidar Mas'ud Alfanda (TDLI, SJTU)

Past week

• The light output has been amplified to twice its original level. This was due to wrong voltage setting, it is now fixed
• Continued to work on the DarkSHINE CDR manuscript

Plan for this week

• Non-uniformity test for the plastic scintillator
• Participate in the wafer test

11:25 → 11:35 Status

Speaker: Matthias Tartarin (TDLI, SJTU)

Today's focus: 

[Hyy*]:

• Fake study: Discussion last Thursday organised by AC, about best strategy to adopt following messages I sent on Mattermost days before. Strategy has been approved, the new MxAOD should now have all of the information to properly define the fakes and to make the study.
• According to the direction validated, I corrected all of my codes. They are ready to be used the minute the new MxAOD will be produced.

[ssWW]:

• WZ_CR: Additional plots (i.e. stacked histogram comparison before/after m_jj WZ_QCD reweighting) to match with legacy analysis have been created. For now it used as input current version of the n-tuples (reminder: Baihong is producing new versions).

 

                                    (left: Screenshot taken from legacy article)                                       (right: Reproduction for our analysis, with current n-tuples)

• Presentation of these results to the group (both reweighting and impact on the distributions) should follow right after newly created n-tuples. 
   
• EWK GM status report: Slides have been prepared. Still raw material for now, I will improve the content over the next couple of days and sent it on Mattermost to get comments from the group.
   

[ZZy]:

• Framework: HGamGamStar framework is now working for the Run 3 samples, for selections that should be more than enough for the kick-off. 
  My current study is on a single and random Data22 file, so low statistics. But the output is readable, and the branches have been identified. 
• Production of results: Consequently, new scripts created to produce graphs and plots of interest: Cutflow yields, and figures identified from the legacy analysis (histograms of variable of interest).

 

---

Immediate Plans: 

 

• [ZZy]: Produce as many plots as possible. Only limitation now: Available datasets I can use. Will check the status this afternoon.
• [ssWW]: Wait for the new n-tuples, re-run the plotting scripts. If results are satisfactory, present them to the group.
