Differences between Monte Carlo models for DIS at small-χ and the relation to BFKL dynamics

Rathsman, J. LU (1997) In Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 393(1-2). p.181-187
Abstract

The differences between two standard Monte Carlo models, LEPTO and ARIADNE, for deep inelastic scattering at small-χ 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.
