This package provides a library of C++ classes which can be used to evaluate and validate reconstruction of charged particle tracks measured by a tracking detector. One of the objectives of this library is to design and implement such functionality in a detector-independent way that can be applied to most common detector configurations, reconstruction algorithms, and frameworks used in particle physics experiments.

The code and coding style in this project are heavily based on and influenced by the ROOT framework. The source is available at https://github.com/plexoos/travex and the doxygen generated documentation can be found at http://plexoos.github.io/travex

The Concept

This tools is designed to answer the following questions:

• Given a hit produced and reconstructed in the detector (i.e. the hit is available for reconstruction), what is the probability to assign this hit to a reconstructed track?

• Given a hit assigned to the reconstructed track, what is the probability for this hit to be the actual (i.e. true) hit produced by the track?

The following entities must be provided by the user:

• A reconstructed track
• A set of hit candidates for the track node in question
• A condition to select the best candidate
• Info what hit was accepted by the reconstruction algorithm (in case of not skipped layer)

How to build and install the library

Prerequisites

• C++ compiler with C++11 support (e.g. g++ >= 4.8.2)
• ROOT (>= 5.34.30), http://root.cern.ch
• boost libraries (>= 1.54): program_options, regex, and filesystem

Build with cmake

Checkout the code using the following command:

git clone https://github.com/plexoos/travex.git

Compile and build the library and the tools:

cd travex/
mkdir build && cd build
cmake ../
make install
