| Abstract: | Production and properties of alp-meson under the extreme hot dense matter which is formed in Au + Au collisions at RHIC energy have been briefly reviewed. The issues are focused on transverse momentum (PT) spectra of φ, elliptic flow of φ, nuclear modification factor of φ, the ratio of Ω(PT)/φ(PT) versUS PT, the ratio of Ω(PT/3)/φ(PT/2) versus PT/nq, spin alignment of φ and the enhancement of φ etc. These observables give the significant information of the strange quark dynamics in hot dense matter under the extreme condition. |
