CASCADE3
Hadron level Monte Carlo generator for ep and pp scattering applying Transverse Momentum Dependent (TMD) parton densities and parton shower.


The Monte Carlo program CASCADE generates a full hadron event record according to the HEP common standards.

CASCADE was originally intended for small x processes and used only gluon chains in the initial state cascade.

With the development of the Parton Branching TMDs, which are valid over a large range in x and Q2, new developments were possible in CASCADE3:

CASCADE3 (apart from the older features) makes use of LHE files (either from collinear NLO calculations like MC@NLO or off-shell calculations from KaTie/Pegasus) and has a full flavor initial state parton shower, which follows directly the TMD from the Parton Branching method.

Different sets of TMDs are now accessed via TMDlib.
