Novel method for producing very-neutron-rich hypernuclei via charge-exchange reactions with heavy ion projectiles

Abstract

We propose a novel method for producing very-neutron-rich hypernuclei and corresponding resonance states by employing charge-exchange reactions via pp(${}^{12}$C, ${}^{12}$N $K^{+}$)n$\Lambda$ with single-charge-exchange and ppp(${}^9$Be, ${}^9$C $K^{+}$)nn$\Lambda$ with double-charge-exchange, both of which produce $\Lambda K^{+}$ in a target nucleus. The feasibility of producing very-neutron-rich hypernuclei using the proposed method was analysed by applying an ultra-relativistic quantum molecular dynamics model to a ${}^6$Li+${}^{12}$C reaction at 2 $A$ GeV. The yields of very-neutron-rich hypernuclei, signal-to-background ratios, and background contributions were investigated. The proposed method is a powerful tool for studying very-neutron-rich hypernuclei and resonance states with a hyperon for experiments employing the Super-FRS facility at FAIR and HFRS facility at HIAF.
