| Abstract: | The effect of the choice of the background on the pion source parametersin two-Pion interferometry analyses in relativistic heavy-ion collisions is studied withthe two-Pion interferometry at small relative momentum. The analytic relationsbetween the pion source parameters from two-Pion interferometry analyses withdifferent backgrounds are obtained, and comparison is made with the experimentalmeasurements of the cental relativistic heavy-ion collisions of 1.8A GeV Ar+Pb . |
