Multiplicity distribution of colour dipoles at small~x
G. P. Salam
Abstract
The colour dipole multiplicity distribution is analysed for the wave function of a heavy onium state at small x. Numerical results for the average multiplicity and the effect of cutoffs on its power growth are presented. Then, the full multiplicity distribution is analysed: the second multiplicity moment is derived and the tail of the distribution is shown to behave as (-2 n). These results are confirmed by a Monte Carlo simulation which also gives the fluctuations in the spatial density of dipoles.
