Effect of Chiral Symmetry Restoration on Pentaquark ${\Theta }^{+}$ Mass and Width at Finite Temperature and Density

Xuguang Huang, Xuewen Hao, Pengfei Zhuang

We investigate the effect of chiral phase transition on the pentaquark ${\Theta }^{+}$ mass and width at one-loop level of $N{\Theta }^{+}K$ coupling at finite temperature and density. The behavior of…
