Repulsion and absorption of the $\Sigma$-nucleus potential for ${\Sigma }^{-}$-${}^5$He in the ${}^6$Li(${\pi }^{-}$, $K^{+}$) reaction

Toru Harada, Ryotaro Honda, Yoshiharu Hirabayashi

We study phenomenologically inclusive spectra of the ${}^6$Li(${\pi }^{-}$, $K^{+}$) reaction at 1.2 GeV/$c$ within a distorted-wave impulse approximation with the optimal Fermi-averaging $π^…
