In--Flight ($K^{-},p$) Reactions for the Formation of Kaonic Atoms and Kaonic Nuclei in Green function method

Abstract

We study theoretically the kaonic atom and kaonic nucleus formations in the in--flight ($K^{-},p$) reactions using the Green function method, which is suited to evaluate formation rates both of stable and unstable bound systems. We consider ${}^{12}$C and ${}^{16}$O as the targets and calculate the spectra of the ($K^{-},p$) reactions. We conclude that a no peak structure due to kaonic nucleus formation is expected in the reaction spectra calculated with the chiral unitary kaon--nucleus optical potential. In the spectra with the phenomenological deep kaon--nucleus potential, we may have possibilities to observe some structures due to kaonic nucleus states. For all cases, we have peaks due to the kaonic atom formations in the reaction spectra.
