Looking at Dark SHINE  background process (inclusive samples from Tong) for positron model

Running optical simulation for PFA

DSS Acts WIP

4 Status

Speaker: Zhiyu Zhao (TDLI, SJTU)

• Paper works
• Time resolution of LYSO
  • Preliminary result: 0.6~1ns(4cm~16cm LYSO)
  • Next to test smaller samples

8 Status

Speaker: Ngoc Khanh Vu (TDLI, SJTU)

Dark Photon Combination:

• Updated the INT note, ready for the EB meeting in March 15th (Friday next week).
• Qibin is working to produce the pulls and ranking of systematic uncertainties in the heavy higgs combination.
• Working on the paper draft.

Xbb tagger g->bb calibration:

• Checked data/MC in tagged and anti-tagged regions of exclusive large-R jet pt bins for large-R jet mean secondary vertex mass, using new dijet samples with new Xbb tagger: GN2Xv01 at 80% WP. 
• Performing template fit to data on large-R jet mean SV mass distribution including both tagged and anti-tagged regions for each pt bin, only statistical uncertainty added.
• results will be updated in the Xbb tagger meeting next week.

9 Status

Speaker: Rui Yuan (TDLI, SJTU)

Hyy*/Hzy: 

• bkg modelling study: got the package for this study from H->μμ group, already can successfully run. Also got a test sample (ntuple), need to transform to workspace and histograms, the test is on-going and also need to migarate to a new environment
• help to prepare a final version of JOs for signal

H2a4b:

• finalize the validation of exclusive Z(ll)H , H->aa, will submit to convener and re-active the MC request in 1~ 2day

DarkSHINE:

• work with chunxiang to prepare simulation of prototype, 1) to store and grep the variable in a efficiency way 2) to define the varible we need for shower range definition 

Other:

• prepare proposal for general postdoc fundation. / modify proposal for NSFC, 
• atlas shift

Speaker: Tong Sun (TDLI, SJTU)

positron on target:

• add truth information for final state  particles of e+ e- -> A, A'
• gennerate signal sample (5e5/mass point)
