pi-Xi correlations in d+Au and Au+Au collisions at STAR
Abstract
Qualitative comparison of source sizes from pi-Xi correlations analyses in d+Au and Au+Au collisions at sqrt(sNN)=200G GeV and sqrt(sNN)=62 GeV is presented. For the most central Au+Au collisions at sqrt(sNN)=200 GeV we report first quantitative results concerning size of the pi-Xi source and relative shift of the average emission points between pi and Xi showing that the homogeneity region of Xi source is smaller then that of pion and significantly shifted in the transverse direction.
