MonoXSMS

Repository for storing the code and results for studies related to LHC Mono-X searches and simplified models (SMS).

Repo Description

• Cards: Cards for generating events with MadGraph5
• modelFiles: UFO files for the Simplified DM models
• notebooks: Jupyter notebooks for recasting and plotting
• Refs: Useful links to references
• CMS-EXO-20-004: Stores auxiliary data from ATLAS and CMS, along with instructions to produce the validation results scripts used, details about the event generation, and the recasting results.

External Packages

Currently the following tools can be installed and might be needed for running the recasting codes:

• MadGraph5¹
• Delphes
• Pythia8
• HepMC
• MadAnalysis5²

Executing:

./installer.sh

Will try to fetch the required packages and install them in the current folder.

Additional Dependencies

The following packages/tools must already be installed in the system:

• autoconf
• libtool
• gzip
• bzr
• ROOT

In addition the variable $ROOTSYS must be properly defined.

For installing ROOT the following steps can be taken:

1. Download the tarball from ROOT releases
2. Install all the required dependencies (see ROOT dependencies)
3. Extract the tarball to root-src
4. Make the build and installation dirs (mkdir root-build root-)
5. In the buld folder run:

cmake ../root-src -DCMAKE_INSTALL_PREFIX=$homeDIR/root-<version> -Dall=ON -Dmemstat=OFF
make
make install

Footnotes

1. In recent python versions the installation of LHAPDF6 through MadGraph might fail, because it uses an old LHAPDF version. In order to install it, one needs to modify the lhapdf6 version to its latest version in MG5/HEPTools/HEPToolsInstallers/HEPToolInstaller.py and run (within the MG5 folder):

   ./HEPTools/HEPToolsInstallers/HEPToolInstaller.py lhapdf6

2. The Delphes card for the MadAnalysis5 implementation of CMS-EXO-20-004 must be replaced by Cards/delphes_card.dat in order to probably treat the DM particles with PDGs 51 and 52. ↩
