Abstract: ROOT is an object-oriented C++ framework conceived in the high-energy physics (HEP) community, designed for storing and analyzing petabytes of data in an efficient way. Any instance of a C++ class can be stored into a ROOT file in a machine-independent compressed binary format. In ROOT the TTree object container is optimized for statistical data analysis over very large data sets by using vertical data storage techniques. These containers can span a large number of files on local disks, the web, or a number of… Show more

“…For multi-dimensional fits, we decided to use the MINUIT algorithm [8], the primary fitting package used in experimental particle physics, which is available through the ROOT framework [2]. The MINUIT package was developed in 1970s to provide several different approaches to function minimization, including several tools for error estimation and parameter-correlation calculation.…”

“…We then use algorithms from the MINUIT package [8], available through the ROOT framework [2], to fit this linear approximation at point x 1...n of our model to the data. The second derivative (quadratic dependence) can be introduced as well:…”

“…The LHC experiments store data and experiment-specific MC events in compressed ROOT format [3]. To store events generated by MC models in a more generic and exchangeable way, HEPMC [4], STDHEP [5], HepML [6] and the Les Houches event format (LHEF) [7] file formats have been developed.…”
