英文摘要 | We investigate the effect of chiral phase transition on the pentaquark Theta(+) mass and width at one-loop level of NTheta(+)K coupling at finite temperature and density. The behavior of the mass, especially the width in hadronic medium is dominated by the characteristics of chiral symmetry restoration at high temperature and high density. The mass and width shifts of positive-parity Theta(+) are much larger than that of negative-parity one, which may be helpful to determine the parity of Theta(+) in high energy nuclear collisions.
