Detailed Description

The base class which defines the structure and functionality of all CheckMATE analyses.

This class is a base class all CheckMATE analyses inherit from. It takes care of passing and storing CheckMATE on-the-fly parameters, reading in the Delphes output ROOT files and providing convenient vectors of final state objects for each event.

Constructor & Destructor Documentation

AnalysisBase::AnalysisBase ( std::string  inFile,
std::string  outFol,
std::string  outPre,
double  xs,
double  xserr,
std::map< std::string, std::string >  branches,
std::map< std::string, std::vector< int > >  flags 
)

Constructor function to load the Delphes ROOT file.

The constructor takes various input parameters automatically provided by the CheckMATE code, which includes information about the analysed events, the structure of the Delphes output ROOT file and the directory the output files should be written into. It automatically loads the right branches of the Delphes ROOT file.

AnalysisBase::~AnalysisBase ( )

Destructor function to free pointers and close opened file streams.

Member Function Documentation

void AnalysisBase::loopOverEvents ( )

Internal function that starts the event loop in main().

This function is called by CheckMATE within the programs main() routine. It first runs the user defined 'initialize()' function. It then starts the event loop, during which for each event the final state objects are created and preisolation conditions are applied before the user defined 'analyze()' function is called. After the loop finished, the user defined 'finalize() function is called before all booked cutflow and signal tables are finalised and printed.
