Self-affine scaling from non-integer phase-space partition in ${\pi }^{+}$p and K${}^{+}$p Collisions at 250 GeV/$c$

Abstract

A factorial-moment analysis with real (integer and non-integer) phase space partition is applied to ${\pi }^{+}$p and K${}^{+}$p collisions at 250 GeV/$c$. Clear evidence is shown for self-affine rather than self-similar power-law scaling in multiparticle production. The three-dimensional self-affine second-order scaling exponent is determined to be 0.061$\pm$0.010.
