Factorial correlators and cumulant correlators in pp collisions at 400 GeV/c

Factorial correlators and cumulant correlators are studied in 400 GeV/c pp collisions as a function of bin-bin distance. A power-law behaviour has been found in a certain range of bin-bin distances. The sun-rules which are based on translation invariance have been tested. The second-order cumulant correlators show that the two-particle correlation may weakly depend on the average multiplicity.
