Differences between Monte Carlo models for DIS at small-x and the relation to BFKL dynamics
The differences between two standard Monte Carlo models, Lepto and 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
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.Comment: 10 pages Latex, 4 eps figure
