Outline of Final Research Achievements

The purpose of this study is to search for H-dibaryon by developing and constructing a new type pictorial detector (TPC). The H-dibaryon is produced in K-nucleus reaction and decays to several particles including short-life hyperons. In order to detect these particles, a TPC which has a target inside and can be operated at high intensity beams is an ideal detector. We have made a proto-type TPC with a newly developed GEM and succeeded to operate the TPC up to 1 MHZ beam intensity without any problem. Based on this study, we have constructed a full-size TPC which made the H-dibaryon search experiment possible and ready at J-PARC.
