  1. HES-HKS & KaoS meeting Toshi Gogami 23/Feb/2012

  2. Contents • SNP school 2012 • GCOE international symposium • Analysis • K+ survival ratio for high multiplicity data • Missing mass shape

  3. SNP School 2012 (2/12-2/18) Lecture Younger’s session J-PARC tour Excursion Sakunami 2 Sakunami Italian restaurant in Sendai

  4. GCOE international symposium(2/20 – 2/22)

  5. K+ survival ratio after Cherenkov cut(for high multiplicity data) • K+ increased..?! <-- bad fitting 52Cr target K+ π+ WC p For CH2 target K+ : ~90%  p : <2%, π+ : <1%

  6. K+ survival ratio after Cherenkov cut(for high multiplicity data) (accut,wccut) = (30,1.2)50204.3pi suv. ratio: 1.05464+-0.00468431K  suv. ratio: 0.927891+-0.00575p  suv. ratio: 0.224177+-0.000961648(accut,wccut) = (30,1)51212.9pi suv. ratio: 1.02391+-0.00458091K  suv. ratio: 0.946533+-0.00583548p  suv. ratio: 0.34468+-0.00124973(accut,wccut) = (30,0.8)52219.8pi suv. ratio: 1.0174+-0.00455897K  suv. ratio: 0.965142+-0.00592067p  suv. ratio: 0.521888+-0.00163598(accut,wccut) = (30,0.5)53464.4pi suv. ratio: 1.01098+-0.00453734K  suv. ratio: 0.988145+-0.00602577p  suv. ratio: 0.793506+-0.0021899(accut,wccut) = (30,0)54105.8pi suv. ratio: 1+-0.00450029K  suv. ratio: 1+-0.00607985p  suv. ratio: 1+-0.00259605 52Cr target K+ WC p

  7. Shape of the Missing mass p  Λ momentum ↓ Angle ↓ • m2 = p2( 1/β2 – 1 ) • Momentum resolution • Tale of the missing mass •  Angular resolution

  8. Summary and Outlook • Summary • SNP school 2012 (2/12 – 2/18) • GCOE symposium (2/20 – 2/22) • Analysis • K+ survival ratio for high multiplicity data • Missing mass shape study • Outlook • E01-011 • ENGE + SPL GEANT4 • TOSCA 来週千賀さんと • E05-115 • Trigger efficiency (Chiba study) • Tracking efficiency • K + Cut efficiency for high multiplicity data • Matrix • JLab 出張 • 3/6 – 3/21 • 物理学会 (関西学院大学) • 3/23 – 3/27 (前日入り)
