Research Abstract

The aim of this research was to reveal the nature of ∧ (1405) resonant state by stopped K-reaction with J-PARC E15/E17 experimental setup, and an experimental proposal, P30, has been submitted to J-PARC PAC at July 2009. The preparation of E17, which was to be executed by P30, was advanced, kaon tuning of the K1.8BR beam line was performed, and calibration of main detector, CDS, was performed, so that overall healthiness of the experimental setup was successfully confirmed.
