Analysis flow

Initial ROOT file

Tuning1. Event selection

• Fitting mean+ 2σ etc.

2. Matrix tuning for selected events

3. Create new missing mass spectra

4. Fitting for new MM Output logs

Iteration

After Iteration

2. Create new ROOT file by new matrices

1. Select better matrices• By width(Λ,Σ,12LB)

ROOT file

LOOP

Coding is in progress

Estimate the raster correction functions every loop

Page 10: HES-HKS &  KaoS  meeting

Outlook

• There was a shift due to the raster correctionWill be fix soon

• Scaling factor for the energy loss of CH2 targetNeed to be estimated again

( by using H2O, 12C target data )
