Abstrakt: Forward-backward multiplicity correlations in s+,K+p andpp collisions at 250 GeV/c ( $$\sqrt s $$ =22 GeV) are given for all charges and for the different charge combinations. The correlations are found to be caused predominantly by centrally produced particles. It is demonstrated that this result is an agreement with observations at the ISR and the CERNp $$\bar p$$ -Collider. The results are compared to expectations from LUND, DPM and FRITIOF Monte Carlo models and a geometrical picture relating correlations in hadron-hadron collisions toe+e- data in terms of impact parameters is tested.
