15:00 → 15:10 Schedule / Announcements / Discussion topics

• ILD Group Meeting, April 7
• FCC Week, June 8-12, University of Helsinki

15:10 → 15:15 Higgs to ss study (Iwate)

Speaker: Harukaze Ito (Iwate university)

• ZZ wrong diagram, check sample name
• Identical result with previous study
• Expected zero tau, but observe many, check samples

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

Speaker: Takumi Seino (The university of Tokyo)

• tau reconstruction in order to suppress background
• currently look for method to tag the truth of tau events
• PFA parent particle issue
• Event matching by EventID
• Re-run Marlin to keep PDG
•  

15:20 → 15:25 PFA with machine learning

Speaker: Tatsuki Murata

15:25 → 15:35 TPC distortion study

Speaker: Kanako Watanabe

• started looking into physics analysis, h-->ss, Z-->lepton 
• technical issue with passing collections to jet clustering, solved
• next, to investigate recoil mass, kinematic constraints
• tail in the high mass end, could be from ISR or Overlay events
• physics motivation: QFV decay of Higgs, h-->bs; start training with h-->ss events. 
• Start generating signal events.
•  

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

Speaker: Daniel Jeans

15:40 → 15:45 Higgs self-coupling

Speaker: Bryan Bliewert
