Hadron level Monte Carlo generator for ep and pp scattering applying kt-factorisation and unintegrated PDFs

The Monte Carlo program CASCADE generates a full hadron event record according to the HEP common standards. CASCADE is intended for small x processes. Until now, it uses only gluon chains in the initial state cascade. Different sets of un-integrated gluon densities are available, which all describe HERA F2 data equally well.

Version 2.3.11 of CASCADE has now been released.

This release includes the new uPDFs obtained from precision fit to HERA data and updates on processes for hadron colliders: Z (W)+jets, forward DY, forward jets, J/psi (Upsilon) production (including polarisation), chi_c(b) prodcution, as well as unintegrated quark densities. For Onium production now also the 2S,3S as well as the 2P states are included.

The manual has been published in EPJC, please use this reference to cite

The physics behind CASCADE is described here

A history of changes and updates is here. A installation guide and the full manual is also distributed in the download

A comparison of CASCADE with NLO calcualtions for heavy quark production for HERA and LHC can be found HERA and the LHC workshop can be found in the proceedings part A and part B and the article is here.
