摘要：

A density two-point correlation function calculation and a power-spectrum analysis of non-statistical event-by-event fluctuations in the mean transverse momentum at large multiplicity n is performed. Good agreement with the data of K. Braune et al. is obtained if the p(t)-density function of the exponential form in the transverse mass with an event-by-event fluctuating slope is used. The pattern of the fluctuating slope is Gaussian with the mean determined by the data on [p(t)(n)BAR] for each n, and the normalized standard deviation as the only free parameter taken to be 0.68. In thermodynamical models, the slope fluctuations may be interpreted as fluctuations in the temperature of the hadronic system.
