    11 If you have successfully produced Pythia8 event files in the MadGraph and Parton Shower lecture (Admir Greljo, Ilaria Brivio), copy (or move) the pp->ll (SM and BSM) into the Delphes directory Delphes-3.4.2
     11If you have successfully produced Pythia8 event files in the !MadGraph and Parton Shower lecture (Admir Greljo, Ilaria Brivio), copy (or move) the pp->ll (SM and BSM) into the Delphes directory Delphes-3.4.2

    1313FIXME: find out how these files where named during tutorial

    42421) Open the ({{{pp_ll_sm.root}}} Delphes ROOT tree and explore the branches, plot the electrons transverse momentum.
     43
    43442) Draw the muon and electron multiplicity via the ROOT command line.Do you understand these distributions?
     45
    44463) Compare the leading muon transverse momentum and pseudo-rapidity in the SM and the BSM sample.

    64 You have now produced a Delphes simulated event with the hypothetical CEPC default detector configuration.
     66We will now focus solely on the BSM sample {{{pp_ll_bsm.root}}} in the mu mu final state.
    6567
    66 1) Can you think of 2 detector parameters that determine and drive the sensitivity of the Higgs recoil measurement in this particular final state?
     681) Can you think of 2 detector parameters that determine and drive the sensitivity of the Z' -> mu mu search?
    6769
    68 2) Identify where they are configured in the delphes detector card.
     702) Identify where they are configured in the delphes detector card {{{cards/delphes_card_CMS.tcl}}}.
    6971
    70723) Create two new detector configurations by degrading these two parameters by a sizable factor.
    7173
    72 4) Reproduce a Delphes sample with these new configurations and observe the impact on the recoil mass distribution.
     744) Reproduce a Delphes sample with these new configurations and observe the impact on the reconstructed Z' invariant mass distribution.
