Abstract
We propose to search for Θ + in K+d→ Kpp reaction at pK+=0.5 GeV/c at J-PARC. A large acceptance Hyperon Spectrometer, which consists mainly of a time projection chamber and a 1-T superconducting magnet, will exclusively measure the decay products of Θ +, such that Θ +→ Kp, followed by K→ π+π-, with a mass resolution of 1 MeV at MΘ. We investigated the feasibility of the proposed experiment using a Monte Carlo simulation. As a result, we expect to collect five orders of magnitude Θ + events, assuming a cross section of 300 μb in 15-day beam time at J-PARC.
