MB Tools
This project is a collection of tools devoted to the evaluation of
Mellin-Barnes integrals.
The project has been started
by Michael
Czakon;
currently the web-page is also being updated
by Alexander Smirnov.
The project is at the development stage, so expect more codes to
appear here.
Currently the following codes can be downloaded:
-
MB.m :
version 1.2 of MB (last updated January 2nd, 2009) by
Michal
Czakon,
the main collection of routines for the resolution of
singularities and the numerical evaluation of Mellin-Barnes integrals;
for details
see hep-ph/0511200;
the current version is documented in
the
Manual ;
the distribution contains two example notebooks,
MBexamples1.nb
and
MBexamples2.nb;
-
MBasymptotics.m :
a routine which expands Mellin-Barnes integrals in a small parameter by
Michal
Czakon;
example usage is illustrated in
MBasymptotics.nb;
-
MBresolve.m : a tool
by Alexander Smirnov
and Vladimir
Smirnov realizing another strategy of resolving
singularities of Mellin-Barnes integrals. This code should be
loaded together with MB.m since it uses some of its
routines. For details
see arXiv:0901.0386
-
AMBRE.m : a tool by Janusz Gluza, Krzysztof Kajda and Tord
Riemann for constructing Mellin-Barnes representations. It works
both for planar multiloop scalar and one-loop tensor Feynman
integrals. This is version 1.2, for previous versions and detailed
description of the package with examples see the
home page . The
program is described in
arXiv:0704.2423 and Computer Physics Communications 177 (2007) 879.
-
barnesroutines.m : a tool by David Kosower for automatic
application of the first and second Barnes lemmas on lists of
multiple Mellin-Barnes integrals. An example notebook is included.
The numerical integration routines used by MB require the following
libraries to be installed, either in the current working directory, or
in the global repository for libraries (e.g. /usr/local/lib)
- CUBA
- CERNlib
(only libmathlib.a and libkernlib.a are actually required)
You will also need a Fortran 77 compiler named f77...
