Overview
This is the homepage for the Monte Carlo simulation MCFM. The program
is designed to calculate cross-sections for various femtobarn-level
processes at hadron-hadron colliders. For most processes, matrix
elements are included at next-to-leading order and incorporate full
spin correlations. For more details, including a list of available
processes, view the documentation in postscript
or pdf format.
Examples
There have been a number of papers based on results produced by the
MCFM code, each one corresponding to different processes.

Download
The source is available as a tar'ed, gzip'ed, uu-encoded package. This
should be placed in a new directory and then extracted. The source can
be initialized by running the Install command and then compiled
with make. The code has been developed and tested under
Redhat Linux and Mac OSX, please report any compilation problems under other
operating systems to the authors.
Execution should be carried out in the Bin directory, whilst
some documentation (for example, instructions regarding the format for
the input file) can be found in Doc.

A number of packages can be linked to MCFM, if the user desires:
- CERNLIB
- when linked, the parton densities of
PDFLIB
can be used and n-tuple event output is possible.
- LHAPDF
- when linked, the pdf implementation of the Les Houches Accord
is included.
When running with the native PDF routines of MCFM, additional input
files may be necessary and can be obtained from the relevant
collaboration:
Six gluon amplitudes
In the course of preparing e-Print Archive:
hep-ph/0602185,
we coded various analytic one-loop results for the six gluon amplitudes.
The fortran programs are given
here.
Higgs + 4 parton amplitudes
In the course of preparing e-Print Archive:
ArXiv: 0910.4481 [hep-ph],
