ClusterID:Performance

Single particle ID and fake rates

Compare MCTruth, MCTruth less neutrinos, MCFast + MCTruth Neutrals, MCFast+ClusterCheaterNeutrals, MCFast+ClusterIDNeutrals, MCFast+ClusterIDNeutrals+ClusterIDChargedOutsideTrackerFiducial area:

    Mass plots

    Event selection

Plots of distribution of gamma, charged had, neu had (like in the Snowmass paper)

Can get a range not just a fixed average for distribution of energy

More important is efficiency and fake rate – not enough just to

Say we smear all neutral hads. Must miss some and miss ID frags to be

Neutral hads also to get true estimates.

Tests of ClusterID:

Measure Mass – not really – hadronic events not used to measure Z, W or top mass.

Use mass measure to ID – not really – use event selection/topolocical technique

Can’t get enough accuracy to distinguish Z and W
