  1. Analysis Status of E05115 Chunhua Chen May 09, 2012

  2. Old status FWHM ~1.675MeV σ= 0.529MeV FWHM ~1.775MeV I=20uA+35uA σ= 0.529MeV • Problem:theoptical description is not uniform on whole kinematical space • 12ΛBgs resolution is worse compare to lambda and sigma; • Core excited states does not shown up in 12ΛB;

  3. First Test-increase the weight of 12ΛBgs-momentum tune- HMFW=1.84MeV σ= 403keV mm=-11.41 HMFW=1.80MeV

  4. First Try-increase the weight of 12ΛBgs-angle tune- HMFW=1.708MeV σ= 387keV mm=-11.38 HMFW=1.672MeV • Tips: • Get the balance between momentum and angle for CH2 target • Still Core excited states do not show up

  5. Second Try-Put first core excites status into Mathematical tuning data sets with low statistical weight （w_core<=0.5w_bgs） σ= 377keV mm=-11.36 HMFW=1.90MeV HMFW=1.84MeV • Still Core excited states do not show up

  6. Third Try-Put first core excites status into Mathematical tuning data sets with higher statistical weight(w_core=2w_bgs) σ= 489keV mm=-11.42 HMFW=1.820MeV HMFW=1.793MeV • Tips: • Core excited states show up • 12ΛBgs becomes wider

  7. Preliminary status – 10ΛBe Second Try Third Try

  8. Preliminary status – 9ΛLi KEK-E336 9LBe

  9. n  n Preliminary Result 7ΛHe 6He core E01011 data 3/2+&5/2+ E. Hiyama, et al., PRC53 2078 (1996)

  10. To do • The optics is still not uniformly mathematically described on whole kinematical space; • Continue to do the optical and kinematical tune; • Think about the cross section and other physics • Prepare the thesis;

  11. Outline • Old status • Problems-the optical description is not uniform on whole kinematical space : • 12ΛBgs resolution is worse compare to lambda and sigma; • Core excited states does not shown up in 12ΛB; • First try • Status • Second try • Status • Problem • To do
