A Simple Model for the BFKL-DGLAP Transition in Deep Inelastic Scattering
G. Gustafson, G. Miu
A simple model is presented, which interpolates between the DGLAP and
BFKL regimes in deep inelastic e-p scattering. The model is based on
the CCFM and LDC models, and it is simple enough to provide an
intuitive picture of the transition region between the two domains.
Results are presented for both fixed and running coupling; for fixed
coupling the transition between the domains occurs at a constant ratio
between ln((k_T)^2) and ln(1/x), while for a running coupling it
occurs for constant ratio between ln(ln((k_T)^2)) and ln(1/x).
