Title Analysis of Deep Inelastic Scattering with z-Dependent Scale
Contributors
Abstract Evolution of the parton densities at NLO in alpha S using W squared = Q squared (1 - z)/z instead of the usual Q squared for the scale of the running coupling alpha S is investigated. While this remormalisation scale change was originally proposed as the relevant one for x --> 1, we explore the consequences for all x with this choice. While it leads to no improvement to the description of DIS data, the nature of the gluon at low x, low Q squared is different, avoiding the need for a 'valence-like' gluon.
