Abstract：
The oscillatory behavior of H moments obtained from the experimental data in pp and pp collisions is studied in the Three-Fireball Model (TFM). It is found that similar to that in the negtive binomial distribution (NBD), the H moment in the full TFM distribution is a monotonic function of q, but oscillates when the distribution is truncated by a not too large value of n_cut. This shows that H moment oscillation is not a special property of pQCD or NBD, but is common for many truncated multiplicity distributions.
