On Feynman scaling in fragmentation region viewed from the collider data

Abstract

The problem in the criterion often used to judge whether the Feynman scaling in fragmentation region is violated or not is discussed. Subtracting the contamination of central region particles from the large pseudo-rapidity region by Monte-Carlo simulation, the reasonable pseudo-rapidity distribution in fragmentation region is obtained and a possible signal on the scaling violation in fragmentation region is seen.
