Kinematic edges: l+l- edge RPC
- The l+l- invariant mass from the decay chain (right) has a kinematic endpoint.
- For 100 fb-1, edge measured at 109.10±0.13(stat) GeV
- Dominant systematic error on lepton energy scale also ~0.1%
- In progress:
- incorporation of widths,
- decay matrix elements,
- polarisations,
- photon radiation, etc
