The Linear Correlation Coefficient vs. the Cross Term in Bose-Einstein Correlations
摘要
We investigate the nature of the new cross term for Gaussian parameterizations of Bose-Einstein correlations of identical particles emitted from purely chaotic hadron sources formed by relativistic heavy ion collisions. We find that this additional parameter in the so-called Bertsch parameterization can be expressed in terms of a linear ``out-longitudinal'' correlation coefficient for emission of bosons and two already known ``radius'' parameters, and . The linear correlation coefficient is of kinematical nature and can be used to determine the widths of longitudinal momentum distributions.
