OVERVIEW
========
This file contains a list of processes that has been used to validate
gosam.
gggg g(k1)+g(k2) -> g(k3)+g(k4) @ alpha_s^4
Purely gluonic process without quark-loops, only one helicity.
Comparison with analytic formula
Calculation is done using 't Hooft-Veltman
gggg_dred g(k1)+g(k2) -> g(k3)+g(k4) @ alpha_s^4
Purely gluonic process without quark-loops, only one helicity.
Comparison with analytic formula.
Calculation is done using dim. reduction
gggg_tree g(k1)+g(k2) -> g(k3)+g(k4) @ alpha_s^2
Tree-Level only. Includes helicities which are known to be zero.
gggz g(k1)+g(k2) -> g(k3)+Z(k4) @ alpha_s^3 alpha^1
This is a loop-induced process.
yyyy gamma(k1)+gamma(k2) -> gamma(k3)+gamma(k4)
Comparison with analytic formulae from literature
WpWpjj u(k1)+d~(k2) -> c~(k3)+s(k4)+e+(k5)+ne(k6)+mu+(k7)+nmu(k8) @ alpha_s^4 alpha^4
Comparison with single phase space point of arXiv:1007.5313v???
uudd u(k1)+u~(k2) -> d(k3)+d~(k4) @ alpha_s^4 alpha^0
Calculation is done using 't Hooft-Veltman
uudd_dred u(k1)+u~(k2) -> d(k3)+d~(k4) @ alpha_s^4 alpha^0
Calculation is done using dim. reduction
dgdg d(k1)+g(k2) -> d(k3)+g(k4) @ alpha_s^4 alpha^0
Calculation is done using 't Hooft-Veltman
dgdg_dred d(k1)+g(k2) -> d(k3)+g(k4) @ alpha_s^4 alpha^0
Calculation is done using dim. reduction
udene u~(k1)+d(k2) -> e-(k3) + \nu_e~(k4) @ alpha_s^2 alpha^2
Calculation is done using 't Hooft-Veltman
udene_dred u~(k1)+d(k2) -> e-(k3) + \nu_e~(k4) @ alpha_s^2 alpha^2
Calculation is done using dim. reduction
udeneg u~(k1)+d(k2) -> e-(k3) + \nu_e~(k4) + g(k5) @ alpha_s^3 alpha^2
Calculation is done using 't Hooft-Veltman
udeneg_dred u~(k1)+d(k2) -> e-(k3) + \nu_e~(k4) + g(k5) @ alpha_s^3 alpha^2
Calculation is done using dim. reduction
setup.in.template:
One can specify options (on top of the usual configuration files)
for all examples by creating a file setup.in.
Care has to be taken not to put process specific options into
that file.
If no such file exists, only the default values and the values
from config files (such as ${HOME}/.golem) are used.
summarize.sh:
By running summarize.sh the user obtains a printout of the status
of all processes for which 'make test' has been run earlier.
Note that 'make test' is not invoked by this script.
runtests.sh:
This script runs 'make test' for all subdirectories.
HOW TO RUN THE EXAMPLES
=======================
After gosam has been successfully installed via the setup script
(python setup.py install) each example can be run by executing 'make test'
for the respective subdirectory. The script 'runtests.sh' can be invoked to
run all tests. The script 'summarize.sh' gives a one-line summary for each
test that has been run so far. By setting up the file 'setup.in' (see
setup.in.template) one can impose default options for all tests.
AUTHORS
=======
In case you encounter failing tests, please, contact the authors. Bug reports,
including the corresponding 'ntest/test.log' can be sent to
Thomas Reiter <thomasr@nikhef.nl>
