| 中文摘要 | Based on the UrQMD transport model, the transverse momentum and the rapidity dependence of the Hanbury-Brown-Twiss (HBT) radii R-L, R-O, R-S as well as the cross term R-OL at SPS energies are investigated and compared with the experimental NA49 and CERES data. The rapidity dependence of R-L, R-O, R-S is weak while R-OL is significantly increased at large rapidities and small transverse momenta. The HBT `lifetime' issue (the phenomenon that the calculated root R-O(2) - R-S(2) value is larger than the correspondingly extracted experimental data) is also present at SPS energies. |
