1 Systematic on Rear Leakage correction Observation : Different behaviour between Data & MC

2 Data TB 2007 / TB 2010 C_leak = A(E) – Slope * F2 Slope : no dependance with E in first approximation

3 F2 Erec/Ebeam With Approximate option

4 MC : 20 – 300 GeV Example of fits F2 Erec/Etrue

5 Comparison TB/MC Compatible with flat for MC -Trend to drop with E with TB data -Flat or increasing for MC E_TB / Etrue (GeV)

6 TB2010 : A Fit with /without : Approximate option A currently calculated on event by event basis - Reflect the tendancy - Point at 300 GeV ? Current approximation of A(E) event per event

7 ISS Data Approximate Etrue with the energy of the integrated profile. Black/Red : 4 month data Grey/Orange : profile H Green : current guess of A per event

8

9 TB2010 : slope Etrue (GeV)

10 Systematics on Cleak A : - 2% Difference observed at 300 GeV (TB) Slope : + 15 % Change of slope in MC >> 300 GeV 1 TeV

11 MC : Fit of “0.025”
