Status of the ZZ fusion analysis (from Aidan Robson):
=========================================
- we now have working flavour tagging, and have an efficiency/purity study in place on an old dataset
- we have the new signal files locally and are just starting to look at them
Status of the H->WW*->qqlv analysis (from Nigel Watson):
=============================================
For the WW fusion (qqlv final state) we have:
- generated ntuples from the signal DSTs for 1.4 TeV CLIC_ILD
- initially used the Marlin IsolatedLeptonFinder with the LAL/jet finder based id,
- put together a TMVA-based selection following plans I showed remotely at the CLIC workshop in Jan.
- as we did not have the backgrounds for CLIC_ILD at 1.4 TeV we started using ILC DBD samples at 1 TeV, to exercise the ntuples
- downloaded and started ntuple creation for the 350 GeV CLIC_ILD, 1.4 TeV CLIC_SID and 3 TeV CLIC_SID, as these had some older, existing background samples so could try to optimise selection of signal in the presence of background.
- Concentrated on 1.4 TeV CLIC_SID, but found problems with using Marlin for these (not tracked down yet, must be my mistake); if CLIC_ILD background samples available soon, will just use these instead rather than CLIC_SID.
