    1. HES-HKS & KoaS meeting 24Jan2014 ToshiGogami

    2. Contents • Blind analysis

    3. Distorted matrices • HKS • xRP : 0.2*xRP mm , 0.2 mm • x’RP: 0.5 mrad , 0.2 mrad • yRP: 0.0 mm , 0.0 mm • y’RP: -3.0 mrad , 100.0 mrad • HES • xRP : -0.8 mm , 0.7 mm • x’RP : 0.0 mrad , 5.0 mrad • yRP : -1.0 mm , 0.7 mm • y’RP : -1.0 mrad , 5.0 mrad

    4. Missing mass spectra with initial matrices

    5. Tuning conditions • Event selection • Λ, Σ0 : +/- 1σ • 12ΛB g.s. : +/- 2σ • Backgrounds • Λ, Σ0 : Realistic distributions and S/N • 12ΛB g.s. : Uniform distribution and realistic S/N • Tuning (five iterations a loop) 67.5 hours in total

    6. Movies

    7. Results Mean values FWHM Λ , Σ0 : 1600 keV 7ΛHe : 1000 keV 他 : 500 - 800 keV ±100 keV
