Readme

This code performs staged BDT analyses using root files as in- and output format.

Dependencies

• ROOT version ≥ 6.05.02 and compiled with TMVA and MathMore
• fastjet
• fastjet contrib (must be compiled with CXXFLAGS=-fPIC)
• Boost (Optional, Range, Units, Operators)

The BoCA code makes heavy use of modern C++ features. The limiting factor for the minimal supportet compiler version is given by the use of return type deduction. Therefore the compiler version must be

• GCC version ≥ 4.9
• Clang version ≥ 3.3

Installation

• the following is tested on recent ubuntu and mac installations

mkdir build
cd build
cmake ..
make

• for quicker compilation (install ccache and ninja-build)

mkdir build
cd build
cmake -G Ninja ..
ninja

• for mac (still install ccache)

mkdir build
cd build
cmake -G Xcode ..
xcodebuild

• if you have trouble installing ROOT ≥ 6 with GCC ≥ 5 you can configure it with

cmake -DCMAKE_CXX_FLAGS=-D_GLIBCXX_USE_CXX11_ABI=0 -Dmathmore=ON -Dbuiltin_gsl=ON -GNinja..

Usage

Examples are listed here.

Each analysis needs a dedicated Analysis class, a set of Tagger classess and a main.cpp file. The Analysis class contains the global information of the analysis, such as file names, path names, variables names etc. Every Tagger class tags or reconstructs one specific particle or signature. Each analysis needs at least one dedicated Tagger. The main.cpp defines the order in which each Tagger is passed to the Analysis.
