在RMFT和MIT口袋模型的框架内研究了超子-超子(YY)相互作用强度对中子星物质内强子-夸克相变的影响.研究发现,中子星内强子-夸克相变与YY相互作用强度是有关联的.弱YY相互作用使得中子星内更容易发生强子-夸克相变.强YY相互作用则使得中子星内超子含量增多.温度升高,YY相互作用强度的影响会减弱.
The influence of the strength of the hyperon-hyperon (YY) interaction on the hadron-quark phase transition in neutron stars is investigated. Results show that whether the quark phase can appear in neutron stars has relation to the strength of the YY interaction. The weak YY interaction leads to lower thresholds for the hadron-quark transition while the strong YY interaction leads to larger amount of hyperons. The increase of temperature suppresses the effects of the strength of the YY interaction.
