• investigate MC tau
• primary tau come from parent 11 (electron)
• remove double-counting tau: FSR
• may still 

15:15 → 15:20 Higgs to ss study (Tokyo)

Speaker: Takumi Seino (The university of Tokyo)

• revise LCWS proceedings; sent to collaborators
• true jet processor investigation; many unexpected elements; merge glue-jets manually; almost ready for applying to signal 4-jet events
• no input parameter for truejet processor; only need PFOs / MCParticles / MCTruthLink collections
•  

15:20 → 15:25 PFA with machine learning

Speaker: Tatsuki Murata

15:25 → 15:35 TPC distortion study

Speaker: Kanako Watanabe

• investigating flavor tagging performance, distribution of btag, bbartag for two jets events look strange: 
• signal events by whizard: hack SM mode h-->bb into h-->bs, by modifying Pythia decay table
• next to do detector simulation
• benchmark point BR(h->bs)~0.1%

15:35 → 15:40 effect of MDI design on TPC beamstrahlung background at FCCee

Speaker: Daniel Jeans
