FCC-ee Workshop on Particle Flow Reconstruction

Europe/Zurich
CERN

CERN

Anna Zaborowska (CERN), Dolores Garcia (CERN), Lena Maria Herrmann, Michele Selvaggi (CERN)
Description

This workshop is meant to discuss in details the particle flow approaches for the experiments on the Future Circular Collider (FCC-ee).

The first three days feature introductory talks and overview of theย work at LHC and in neutrino experiments (modern Pandora developments), with the main part of the event dedicated to theย FCC-ee detector concepts: current work on Pandora implementation and Machine Learning approaches.

The last two days of the event are dedicated to the hands-on sessions/hackathon and the discussions on the evolution of particle flow for FCC-ee.

ย 

Please note that the timetable is still a first draft, we are waiting for confirmations from the speakers.
