New techniques in particle reconstruction for VBS

22 Oct 2018, 10:00 → 24 Oct 2018, 14:20 Europe/Zurich

Krakow

Henning Kirschenmann (Helsinki Institute of Physics (FI)), Lucrezia Stella Bruni (Nikhef National institute for subatomic physics (NL)), Magdalena Slawinska (Polish Academy of Sciences (PL)), Pietro Govoni (Universita & INFN, Milano-Bicocca (IT)), Senka Duric (Kansas State University (US)), Steven Schramm (Universite de Geneve (CH))

This workshop is intended to review the state of the art for the physics object reconstruction in the ATLAS and CMS experiments, identify areas where improvements could benefit VBS analyses and what new techniques may be used and start the work to get them done.

 

The programme will cover modern jet reconstruction, use of machine learning, high-energy leptons reconstruction, VBS final state description.
