Search for the deeply bound $K^{-}pp$ state from the semi-inclusive forward-neutron spectrum in the in-flight $K^{-}$ reaction on helium-3

Tadashi Hashimoto, Shuhei Ajimura, George Beer +64

An experiment to search for the $K^{-}pp$ bound state was performed via the in-flight ${}^3$He($K^{-},n)$ reaction using 5.3 $\times$ $10^9$ kaons at 1 GeV/$c$ at the J-PARC hadron exper…
