A Common Tracking Software (ACTS)
This project contains an experiment-independent set of track reconstruction
tools. The main philosophy is to provide high-level track reconstruction
modules that can be used for any tracking detector. The description of the
tracking detector's geometry is optimized for efficient navigation and
quick extrapolation of tracks. Converters for several common geometry
description languages exist. Having a highly performant, yet largely
customizable implementation of track reconstruction algorithms was a
primary objective for the design of this toolset. Additionally, the
applicability to real-life HEP experiments plays major role in the
development process. Apart from algorithmic code, this project also
provides an event data model for the description of track parameters and
measurements.
Key features of this project include: tracking geometry description which
can be constructed from TGeo, DD4Hep, or GDML input, simple and efficient
event data model, performant and highly flexible algorithms for track
propagation and fitting, basic seed finding algorithms.
