[SLAC] [SLAC Pubs and Reports] SLAC-PUB-7344Differences Between Monte Carlo Models for DIS at Small-X and the Relation to BFKL Dynamics Abstract The differences between two standard Monte Carlo models, {\sc Lepto} and {\sc Ariadne}, for deep inelastic scattering at small-$x$ is analysed in detail. It is shown that the difference arises from a `unorthodox' suppression factor used in {\sc Ariadne} which replaces the normal ratio of parton densities. This gives rise to a factor that qualitatively is similar to what one would expect from BFKL dynamics for some observables like the energy flow and forward jets but not for the 2+1 jet cross-section. It is also discussed how one could use the 2+1 jet cross-section as a probe for BFKL dynamics. (Equations render on Windows, Mac OS, AIX, Linux, Solaris, and IRIX with the techexplorer plug-in.)
