Feasibility study of measuring interaction cross sections of hypernuclei produced in projectile fragmentation reactions with WASA-FRS setup

【摘要】 A novel method is proposed to measure the interaction cross sections of short-lived hypernuclei with the WASA-FRS experimental setup at GSI and FAIR.The interaction cross sections of hypernuclei,produced in projectile fragmentation reactions at relativistic energies,can be determined from their production point distribution within a target.The feasibility of such a measurement is evaluated through detailed Monte Carlo simulations.The results indicate that an aimed uncertainty on the order of 10% can be achieved for the case of a hypertriton,demonstrating the potential of this method for studying matter radii and the possible hyperon halo structure of hypernuclei.更多还原
