CMS Heavy flavour tagging workshop 2018

11 Apr 2018, 08:30 → 13 Apr 2018, 18:00 Europe/Zurich

VUB

Ivan Marchesini (Vrije Universiteit Brussel (BE)), Kirill Skovpen (Vrije Universiteit Brussel (BE))

The workshop brings together high energy physicists to discuss the recent progress in the development of b and c jet identification techniques and its applications in physics analyses at CMS. The main topics of the workshop will cover the latest improvements in the simulation of heavy hadron production at the LHC, the application of deep learning techniques to the identification of displaced reconstructed objects, as well as the latest results from various physics analyses exploiting heavy flavour identification methods.

The main topics of the workshop include:         

   • Simulation of b hadron production and decay        
   • Reconstruction of tracks and vertices        
   • Identification algorithms for heavy flavour jets        
   • Performance of heavy flavour tagging in data        
   • Jet substructure and heavy flavour tagging in boosted topologies        
   • Application of heavy flavour tagging in physics analysis
   • Heavy flavour tagging at future colliders

The first day of the workshop will be devoted to open discussions together with the event generator and theory experts. The workshop then proceeds with CMS internal sessions in the following days. It is the first time that such workshop is organised by CMS.
