Rare process / signal production WIP (downloading en_ecal)

Scan positron rare process bias factor with Tong

More concentrated and flexible signal production workflow:  UFO -> Madgraph -> LHE -> DSimu

    Environment: Update DarkSHINE Docker with hepmc3 lib and madgraph v3.5.4

    coop with Xiang

 

- limit setting by fitting

   - positron corssx (Tong)

   - 0 background mu value (0.6,0.6,0.6) (Xuliang)

   - plot DarkSHINE Analysis (Tong)

   - limit plotting python (Xuliang)

 

- optimize cut (v1.6.4) (Tong / Xuliang)

    - signal sample mass point (Tong)

    - signal sample production (Xuliang)

    - 5e7 inclusive sample on bl0 (Xuliang)

    - 1e11 inclusive sample with truth filter on siyuan mark I (Xuliang)

    - cutflow (Tong)

    - MVA cut opt (Xuliang)

    - new limit

   - BDT

 

- rare process analysis

   - rare process estimation (Tong)

   - rare process production (Xuliang)

DarkSHINE:

1. check the proof for HCAL simulation paper
2. scintillator test: most of the combinations of old/new scintillator/fiber are test ed for a first round, looks like each degree of freedom results in a slight difference in light yield

H2a4b:

received ufo from theoriests, addressing....

trying to dig into ZCharm_easyjets to get first version of framework

 

Hyy*/Hzy:

successfully got spurious signal results from a fake bkg template. next step is to prepare WS by combining signal WS, fake bkg template and fake data

16:00 → 16:10 Status

Speaker: Tong Sun (TDLI, SJTU)

Biasing study for positron on target:

• the rare process rate was obtained after fitting.
• need to organize the results and calculate the cost.

others:

• review a BESIII memo.
• to investigate the BFs of omega-> gamma eta and omega -> eta e+ e- .
