用微观输运模型研究了反K核碰撞中具有奇异性的超碎片S=−1和S=−2的形成机制。在输运模型中模拟了赝标介子和超子的动力学，其中包括了产生超子的所有可能的反应通道，如弹性散射、共振产生和衰变、奇异性交换反应以及介子-重子和重子-重子碰撞中直接奇异性的产生。在相空间中使用聚合方法来构造超碎片，并对统计模型进行修改以描述超碎片的衰变。研究发现，波长−的产生与K+动力学有关。超子、波长和西格玛是在一个宽广的快速区内产生的。核子碎片和超碎片的产生截面弱地依赖于入射动量。λ超片段的产率是级联−超片段的第六个数量级。讨论了在中国高强度重离子加速器装置上进行超核物理实验的可能性。
The formation mechanism of hyperfragments with strangeness s = −1 and s = −2 in collisions of antikaons.on nuclei has been investigated within a microscopic transport model. Dynamics of pseudoscalar mesons.and hyperons is modeled within the transport model, in which all possible reaction channels for creating.hyperons such as the elastic scattering, resonance production and decay, strangeness exchange reaction, and.direct strangeness production in meson-baryon and baryon-baryon collisions have been included. A coalescence.approach is used for constructing hyperfragments in phase space and the statistical model is modified to describe.the decay of hyperfragments. It is found that the lambda− production is correlated to the K+ dynamics. The hyperons.lambda and sigma are created within a broad rapidity region. The production cross sections of nucleonic fragments and.hyperfragments weakly depends on the incident momentum. The yields of lambda hyperfragments are the sixth order.of magnitude of cascade− hyperfragments. Possible experiments on the hypernuclear physics at the high-intensity.heavy-ion accelerator facility (HIAF) in China are discussed.
