Goal: investigate the large excess observed in the EE category with the Exotics selection
1) Summarize what we know so far about EE events (purity, jet-jet contribution, different mass shapes, DeltaEta VS mgg evolution, etc.)
==> Thibault (for Thursday high mass meeting)
2) Check the CC/CU/UU fraction for EE events in the excess region and compare to sidebands and MC
==> Isabelle
3) Look at the shower shapes of the grey photons for EE events (passing loose iso but failing tight iso) and compare to MC
- Start inclusively (in pT) and look in pT bins (as statistics allows)
- Consider also the conversion status
==> Alexis (+Nicolas)
Isabelle: Fraction of grey photons versus eta (splitting in C/U in a 2nd step).
4) Check in MC the tight ID rejection of jets at high pT in the EC
- Use dijet MC sample
- Consider also the conversion status
==> Not immediately, will see the outcome of 3) first.
5) Read the crosschecks note (to not repeat studies already performed)
==> Thibault
