MadAnalysis 5 physics analysis database

This page contains a collection of LHC analyses that have been implemented in the MadAnalysis 5 framework (in the expert mode) described in ​arXiv:1405.3982] and ​arXiv:1407.3278]. For each analysis, a commented C++ code is available for download, provided together with information on the analysis and references to relevant publications. A careful validation of each implementation is also provided.

In order to use these files, you need MadAnalysis 5 version 1.1.11 or higher, as well as our modified version of Delphes, which can be installed with the command

 install delphesMA5tune

within MadAnalysis 5. If you have an older version of MadAnalysis 5, first update it to the latest one.

You then need to create a working directory by starting MadAnalysis 5 as

 ./bin/ma5 -E -R

and follow the instructions displayed to the screen. So far, there is no automatic installation in the form of an analysis library. Instead, analyses have to be added by hand. This is done by running the script newAnalyzer.py (located in Build/SampleAnalyzer), passing as an argument the name of the analysis of interest. For instance,

 python newAnalyzer.py cms_sus_13_011

will create and modify all necessary files for adding the analysis named cms_sus_13_011. In particular, a pair of header and source C++ files cms_sus_13_011.cpp and cms_sus_13_011.h are now available in the subdirectory Build/SampleAnalyzer/User/Analyzer. These files must be replaced by those available for download in the database (see list below). A more convenient library mode to install several analyses at once is in preparation.

After execution of an analysis, exclusion under the CLs prescription can be computed with the Python code ​exclusion_CLs.py It requires ​SciPy to be installed. The path to the working directory of interest has to be provided in the variable analysis_path in the beginning of the code. The limit-setting code can also be obtained with the command

 install RecastingTools

within MadAnalysis 5. This will create a local copy of ​exclusion_CLs.py in every new working directory. In both cases, the code should be called as

 ./exclusion_CLs.py analysis_name mypoint.txt [run_number] [cross section in pb]

The exclusion results will be printed on the screen and in an output file located in the directory mypoint.txt/ of the output of the analysis.

We strongly encourage users to publish their re-implemented LHC analyses via Inspire. This way they not only become part of the public database, rendering them as useful as possible to the community, but they also become individually searchable and citable.

For any information on the implementation of an analysis, on the database or on the expert mode of the program, please visit the 'Answers' section of our ​launchpad page.

[1] This analysis requires MINUIT libraries. Therefore, the line

 LIBFLAGS += -lMinuit

should be added to the Makefile of the Build/ directory before compilation.
