GENUINE HIGHER-ORDER CORRELATIONS IN PI+P AND K+P COLLISIONS AT 250 GEV C/

Genuine higher-order correlations could be established up to fifth ord er in multiparticle Production in pi+p and K+p collisions at 250 GeV/c . At decreasing interparticle distance in invariant phase-space, these correlations follow approximate power-law scaling. The scaling behavi or is different for non-exotic and like-charge particle combinations. It cannot be reproduced by FRITIOF without Bose-Einstein correlations. Including Bose-Einstein correlations according to JETSET7 reproduces the slope of like-charge two-particle correlations, but overestimates diose of the higher orders.
