Abstract：
The bunching parameters and bunching correlators have been calculated by using the pseudorapidity and azimuthal angle distribuhons of charged prides produced in pp collisions at 400GeV/c. The results show that the values of bunching parameter depend not only on the width of mulhplicity distribuhon. but also on the correlation of particles. The bunching parameters η₂ (M) and η₃ (M) follow the same power-law behavior in pseudorapidity and azimuthal angle spaces indicating that the multifractal structure in pp collisions at 400GeV/c is observed. The values of the second-order bunching correlators in pseudorapidity space depend on the width of multiplicity distribuhons and decrease with increasing bin-bin disuse D.
