论文摘要
在相对主义的平均含量模型中研究了光核和超核和重型重子，以及在恒星环境（例如超新星或二元合并）中发现的低密度物质和$δ$ -Baryons的产生。将五个光核与三个轻颈椎一起考虑。 Hyperons和$δ$ -Baryons的存在将簇的溶解转移到更大的密度，并增加了簇的丰度。该效果越小，电荷分数越小，温度越高。 $δ$ -Baryons的耦合被选为核子有效质量在中子恒星内保持有限的质量。
The production of light nuclei and hypernuclei together with heavy baryons, both hyperons and $Δ$-baryons, in low density matter as found in stellar environments such as supernova or binary mergers is studied within relativistic mean-field models. Five light nuclei were considered together with three light hypernuclei. The presence of both hyperons and $Δ$-baryons shift the dissolution of clusters to larger densities and increase the abundance of clusters. This effect is larger the smaller the charge fraction and the higher the temperature. The couplings of the $Δ$-baryons were chosen imposing that the nucleon effective mass remains finite inside neutron stars.
