08:30 → 08:35 Introduction

08:35 → 08:45 Vertex t0 reconstruction in simulated events

• Track-cell matching
• Machine learning

08:45 → 08:55 Vertex t0 in data

• Run 3:
  • calibration
  • cross-talk
  • cell weighting
• Run 4:
  • Calibration using HGTD

08:55 → 09:10 LAr reconstruction

• machine learning pulse shape
• timing optimization
• cross-talk

09:10 → 09:20 HGTD / LAr timing combination

09:20 → 09:30 Jet timing and particle flow

Use of LAr timing to improve particle flow
jet time for delay jets
