【Abstract】 The influence of multiplicity distribution (fluctuation of multiplicity in the event space) on the erraticity behaviour in high energy collisions is investigated via Monte Carlo simulation and compared with the experimental results from NA27 data. It is shown that, the erraticity phenomenon is insensitive to the multiplicity fluctuation. When the average multiplicity is low this phenomenon is dominated by the statistical fluctuations, also in the case of multiplicities fluctuating from event to event.更多还原
