Search for the Pentaquark T+ via the p-p ? K-X Reaction at J-PARC

The T⁺ pentaquark was searched for via the p^- p ? K^- X reaction using a beam momentum of 2.01 GeV/c at the J-PARC hadron experimental facility, taking advantage of high-statistics and high-resolution compared with previous experiments, some of which claimed the evidence of T⁺.
