P-wave resonant state of the HeΣ4 hypernucleus in the He4(K−,π−) reaction
We theoretically investigate a possible existence of a p-wave HeΣ4 resonant state with Jπ=1−, T≃1/2 above the Σ threshold, using a coupled (3N–Λ)+(3N–Σ) model with a spreading potential. We calculate inclusive and Σ–Λ conversion π− spectra in a He4(K−,π−) reaction at 1.5 GeV/c, θlab=4–12° by the Gre...
