Project Descriptions
Tracking Workshop for HEP -- January 2019
Machine Learning Implementation for ambiguity resolution scoring function
Project Goal: Use machine learning to implement a track scoring function for ambiguity resolution
Project Roadmap: 1) Review current implementation of ambiguity resolution in ATLAS tracking code. 2) Develop interface 3) Implement current version of ambiguity resolution 4) Identify and produce appropriate samples for validation and testing 5) Identify ML approach for scoring function 6) Train, test, repeat
Project Participants: Heather Gray, Nick Cinko, you?
Performance Tools
Project Goal:Develop a simple software package within the ACTS framework to be used to evaluate the physics performance of track reconstruction
Project Motivation: It’s vital to check the performance to ensure that the code we’re developing reproduces or improves upon the ATLAS performance! Developing a small package will save time and effort so that everyone doesn’t need to do this for each project
Project Roadmap:1) Code/package design 2) Produce samples for testing 3) Implementation of a basic set of histograms 4) Test out the package with other workshop participants
Project Participants: Heather Gray, you?
ACTS for Testbeam Reconstruction
Project Goal: Use ACTS to reconstruct tracks from hits registered in a 6-plane pixelated telescope.
Project Motivation: Great beginner application, expands user-base, ...
Project Roadmap: (1) Implement simple 6 plane geoemtry (2) Parse data testbeam data from telescope (3) Align planes (4) Fit tracks (Bonus) Account for multiple scattering
Project Participants: Timon, Simone, ...

Implement Belle II geometry (VXD)
Project Goal: Belle II -> ACTS and handle non-cylindrical silicon sensors easily
Project Motivation: Necessary to benchmark ACTS against existing tracking code in Belle II. Potentially generalize to other experiments.

Implement Belle II geometry (CDC)
Project Goal: Belle II -> ACTS and handle drift chambers in ACTS
Project Motivation: Necessary to benchmark ACTS against existing tracking code in Belle II. Potentially generalize to other experiments.

Event Time Extraction with ACTS
Project Goal: Reimplement the χ² fit-based method from Belle II
Project Roadmap:
Project Participants: Nils Braun, Lu Cao, you?
Electron Fitter with Bremsstrahlung
Project Goal: Study the status of the Gaussian sum filter implementation, how this connects to incorporating Bremsstrahlung information
Project Roadmap: This heavily depends on (a) what is already there (and how available it is) and (b) what your personal passion is about :-)
Project Participants: Patrick Ecker, Nils Braun, you?
Vertex reconstruction
Project Goal: Advance primary vertex algorithm development.� a) develop a kalman vertex fitter (bonus: with timing information)� b) develop a vertex finder algorithm (e.g. iterative finder)
Project Motivation: Vertex finding/fitting is a primary ingredient for every tracking software in HEP and it’s currently only barely started in ACTS
Project Roadmap: 1) assess additional event-data-model needs, implement them� 2) implement simple finder or fitter, depending on project
Project Participants: Simone (if someone else joins), ??
ACTS with GPUs
Project Goal: To define a target use case for GPUs within ACTS and provide a roadmap for doing so
Project Motivation: GPUs are a powerful tool for fast processing. Many difficulties to utilization, but
Project Roadmap:
Project Participants: Lauren*, ??
*NB when originally proposed there was some hope that a postdoc would have started to work on this.
