      To do list
      Orateur: M. Thibault Guillemin (LAPP)

      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
