Fifth International Workshop for Future Challenges in Tracking and Trigger Concepts

The International Workshop for Future Challenges in Tracking and Trigger Concepts is a workshop focused on event reconstruction and analysis in modern experiments in High Energy Physics (HEP), especially those built for heavy-ion interactions. The goal of the workshop is to share the experience between the experiments in fast and efficient track and particles finding and to develop common approaches and libraries. The main topics of the workshop are:

• track finding and fitting;
• finding and reconstruction of vertices and short-lived particles;
• parallel computer architectures;
• software implementation for the parallel architectures;
• software architectures and frameworks.

This is a 5th workshop of the series. Previous workshops were organised at

• GSI, 2010
• CERN, 2011
• FIAS, 2012
• CERN, 2012

Recent foci included

• the development of a core common package and common libraries and discussing a shared approach and strategy for track finding, event reconstruction, vertex finding whether primary or secondary as well as sharing ideas on novel approach to face the many-core CPU/GPU era;
• forming a core project team gravitating around the use of the implementation and use of the Cellular Automata (CA) track finder in High Level Trigger (HLT) and offline reconstruction, discussing use and results from the KF Particle packages (vertex finding) as two possible common approaches;
• promoting the use of vectorisation.
