The CCFM Monte Carlo generator Cascade
نویسنده
چکیده
Cascade is a full hadron level Monte Carlo event generator for ep, γp and pp̄ processes, which uses the CCFM evolution equation for the initial state cascade in a backward evolution approach supplemented with off shell matrix elements for the hard scattering. A detailed program description is given, with emphasis on parameters the user wants to change and common block variables which completely specify the generated events.

Hadronic final state predictions from CCFM: the hadron-level Monte Carlo generator Cascade∗
We discuss a practical formulation of backward evolution for the CCFM small-x evolution equation and show results from its implementation in the new Monte Carlo event-generator Cascade.
متن کاملSaturation effects in final states due to CCFM with absorptive boundary
We apply the absorptive boundary prescription to include saturation effects in CCFM evolution equation. We are in particular interested in saturation effects in exclusive processes which can be studied using Monte Carlo event generator CASCADE. We calculate cross section for three-jet production and distribution of charged hadrons.
متن کاملMonte Carlo Generators and the CCFM Equation a
Small-x final states are central to the understanding of small-x evolution in general. To understand final-state properties such as forward jet rates and transverse energy flow, it is important to have event generators which give a good description of the experimental data. It has, however, turned out to be difficult to produce such an event generator. To leading double-log accuracy, the CCFM [...
متن کاملHeavy Quark Production at Hera in Kt Factorization Supplemented with Ccfm Evolution
The application of kt factorization, supplemented with the CCFM small-x evolution equation, to heavy quark production is discussed. Differential cross sections of bb̄ production and also inelastic J/ψ production as measured at HERA are compared to the hadron level CCFM Monte Carlo generator Cascade, using the unintegrated gluon density obtained within the CCFM evolution approach from a fit to HE...
متن کاملHeavy Quark production at the TEVATRON and HERA using kt - factorization with CCFM evolution
The application of kt-factorization supplemented with the CCFM smallx evolution equation to heavy quark production at the TEVATRON and at HERA is discussed. The bb̄ production cross sections at the TEVATRON can be consistently described using the kt-factorization formalism together with the unintegrated gluon density obtained within the CCFM evolution approach from a fit to HERA F2 data. Special...
