【摘要】：本論文首先從QCD的手征對(duì)稱性及其破缺出發(fā)詳細(xì)的介紹了手征對(duì)稱性的非線性實(shí)現(xiàn)、非線性σ模型的拓?fù)湫再|(zhì)以及Skyrme模型的基本思想。接下來(lái),我們介紹了Bogomol’nyi-Prasad-Sommerfield(BPS)Skyrme模型及其對(duì)核物質(zhì)的描述。最后,基于本人的工作,我們研究在K介子存在時(shí)BPS Skyrmion物質(zhì)的性質(zhì):基于探針近似,在平均場(chǎng)的層次上研究BPS Skyrmion物質(zhì)中K介子質(zhì)量的改變;考慮BPS Skyrmion和K介子的耦合研究K介子對(duì)物態(tài)方程以及中子星的質(zhì)量 半徑關(guān)系的影響。
[Abstract]:In this paper, the nonlinear realization of chiral symmetry, the topological properties of nonlinear 蟽 model and the basic idea of Skyrme model are introduced in detail from the chiral symmetry of QCD and its breaking. We introduce the Bogomol'nyi-Prasad-Sommerfield(BPS)Skyrme model and its description of nuclear matter. Finally, based on my work, we study the properties of BPS Skyrmion in the presence of K meson: based on the probe approximation, The change of mass of K mesons in BPS Skyrmion matter is studied at the level of mean field, and the influence of K mesons on the equation of state and the mass radius of neutron stars is studied by considering the coupling of BPS Skyrmion and K mesons.
