Abstract:

We examine the interferometry results of identical pion and kaon for the granular sources of quark–gluon plasma droplets for the Au + Au collisions at √200sNN=200 GeV. The effects of particle absorptions of pion and kaon on the results are investigated. We find that the absorptions lead to the decrease of the interferometry radii. After considering the absorptions, the interferometry radii of pion and kaon of the granular sources are in better agreement with the experimental data of the Au + Au collisions.
