Visible vs true asymmetry, Nikolai’s ntuple
simple re-weighting
m tau- gamma vs m tau+ gamma on all 1) generated ,2) matched
and 3) reconstructed events level (reconstructed masses used)
1)
2)
3)
In 1)2) masses are
calculated from true
momenta, in 3)
masses are
calculated from
reconstructed visible
momenta, no correction
for missing neutrinos.
