Event Categorization in Nuclear Emulsion of E373 Experiment
- KEK-PS E373, a hybrid emulsion experiment, was performed using a separated Kˉ meson beam of momentum 1.66GeV/c at High Energy Accelerator Research Organization (KEK) proton synchrotron (PS). The purpose of this experiment is to study S= -2 nuclei produced via Ξˉ hyperon captured at rest in nuclear emulsion with ten time larger statistics than the previous experiment (E176). Tracks of the Ξ hyperon candidates were searched for and traced in the emulsion using a newly-developed automatic track scanning system. We have analyzed nearly 90% of the total emulsion by automatic and semiautomatic scanning methods. We have found 7 double-Λ hypernucleus events, 2 twin Λ- hypernuclei events and 33 single- Λ hypernucleus events.
