Example of application/running of the code
Prepare the directory
- Duplication of Template directory $>cp -r Template First_test
- Change diretory: $> cd First_test
- Switch to MadWeight mode: $> ./bin/PassToMadWeight
- Parametrize the proc_card.dat. For this example the decay chain is the following one: pp>(W+>e+ve) and the transfer functions is dbl_gauss_pt_jet (the one foreseen for PGS in the CMS-like configuration). You can download this proc_card here.
- Generate the process: $> ./bin/newprocess
- Put the events sample in the ./Events directory under the name input.lhco. Our events sample is generated with MadGraph/Pythia/PGS: and is available here.
Prepare the run
- Configure the MadWeight_card.dat. In the given card, we will run in single machine for 20 events and 5 different mass hyppothesis. As they are no divergencies in the square matrix element, we don't want to put any cut in the evaluation of the integrals. So that we have desactivated the cut.
- Check the param_card.dat Check that you parameter not modified via the MadWeight_card are coherent. In this case we use default file.
- Check the run_card.dat Choose the name of the run (here we use "fermi") , the energy of the beam,... Note that the cuts defined here will not be used (as we have asked in the MadWeight_card.dat). Default files is used
- Define/Check transfer_card.dat. Only the jet part are often consider as process dependant, as far as we don't have jet, the defaulf parametrization (delta function for the electron) should be sufficient.
Launch MadWeight
In this example we will launch MW by step in order to explain in detail each step.
Note the log are done with version: 2.5.4
- $>./bin/madweight.py -1 or $>./bin/madweight.py param:
Create the different param_card and files related to the different cards.

Analyzes the Feynman diagrams, the transfer function and creates the fortran code for the integration.

charge file ./Events/fermi/fermi_weights.out load cross section term ./Events/fermi/fermi_cross_weights.out no acceptance term loaded
At this stage all the output are in ./Events/fermi/ For example the computation of the likelihood (whitout the AcceptanceTerm) gives:
1. 40 228.955053585 0.000715345946119
2. 60 188.48197688 0.000750658557815
3. 80 152.390896814 0.000965491294664
4. 100 159.014840519 0.00113245384668
5. 120 168.413249969 0.00123941979677
The first column is the card_number, the second the W mass, the third the value of the likelihood, and the last one the error associate. In this simple example, we can claim that the correct mass is around 80 GeV. (In this case, the error is dominated by the binning)
