1. HES-HKS & KaoS meeting Toshi Gogami 25/Apr/2013

2. Contents Raster Correction

3. Analysis flow Initial ROOT file ROOT file Tuning LOOP • Event selection • Fitting  mean+ 2σ etc. • Matrix tuning for selected events • Create new missing mass spectra • Fitting for new MM  Output logs • 2. Create new ROOT file by new matrices • 1. Select better matrices • By width(Λ,Σ,12LB) KRD After Iteration Iteration

5. Present Raster Correction Correction OFFSET

6. Correction by a linear function Λ w/o RC

7. Correction by a linear function Λ w/o RC

8. Comparison Present RC w/o RC New RC

9. Coding is in progress Estimate the raster correction functions every loop

10. Outlook • There was a shift due to the raster correction • Will be fix soon • Scaling factor for the energy loss of CH2 target Need to be estimated again ( by using H2O, 12C target data )

11. 他 • 学振PD • 5月9日 締切 ( 受入研究機関必着 ) • Paper (HLAB MEETING) • 履修登録
