Imaging Analysis Of Granular Source In Different Frames

Intensity Interferometry (Hanbury-Brown-Twiss interferometry) is an importanttool for studing time-space structure and dynamics of partical-emitting source producedin high energy heavy ion collisions. Recently, more and more researchers takeadvantage of a kind of new method of Intensity Interferometry, called IMAGINGTechnology. Unlike usual Intensity Interferometry method, IMAGING Technology doesnot depend on the model of source, in the meantime, we can get the intuitionisticgeometric information of source directly by the experimental data.Granular source model was used to explain the HBT puzzle, first of all, weintroduce the2Ï€ correlation and the Imaging technology of granular source in the paircm frame, and we also discuss the imaging analysis of the granular source with variousnumber and radius of droplets. As we known, it is much easier to study the granularsource in the pair cm frame, and at the moment, all of the research of the granularsource is in the pair cm frame, so in this paper, we compare the imaging anlysis of staticuniform source with various momentum distribution, and we demonstrate thesuperiority of the study of granular source in experient frame. We kown that the sourcefunction which we abtain by the imaging analysis does not depend on the momentumdistribution, so the function may truly discribe the time-space structure. Then we obtainthe imaging analysis consiquence of evolving hydrodynamic source, we can get the turesource function curves by limit the energy difference, which means the method isaccurate. At last we gain the source function of granular source by IMAGINGtechnology in experiment frame, according to the source function we can get the truetime-space structure by limit the energy difference as the velocity increase.
