Abstract: One of the main items of the J-PARC E13 experiment is the search for excited states of the \(_{\Sigma }^{4}\text{He}\) hypernucleus via the ^4He(K^−, π^−) reaction at 1.5 GeV/c. The missing-mass spectrum of the ^4He(K^−, π^−)X reaction was obtained in an angular range from 0 to 20°. We show the count-base spectrum of the missing-mass in the angular range from 2 to 14°. The ground state of \(_{\Lambda }^{4}\text{He}\) and \(_{\Sigma }^{4}\text{He}\) were clearly observed in the missing-mass spectrum. We also show three missing-mass spectra divided by the reaction angle.
