v4 v5 70 70 71 71 Note: Most objects are described in terms of pp specific variables (PT, Eta, Phi). 72 This is simply for historical reasons since Delphes was developed originally as a tool for LHC physics. To plot ee-like variables, one needs to write the translation (or make use of the very useful TLorentzVector of ROOT, see part III).72 This is simply for historical reasons (and makes of course no difference whatsoever) since Delphes was developed originally as a tool for LHC physics. To plot ee-like variables, one needs to write the translation (or make use of the very useful TLorentzVector of ROOT, see part III). 73 73 74 74 2) Interactively draw the muon multiplicity and the jet multiplicity. Do you understand these distributions? … … 76 76 == III) Write a simple analysis macro == 77 77 78 0) Write down the formula for the recoil Higgs mass.78 1) Write down the formula for the recoil Higgs mass. 79 79 80 1) You can find a simple analysis macro in "example/Example1.py". It can be executed like this:80 2) You can find a simple analysis macro in "example/Example1.py". It can be executed like this: 81 81 82 82 {{{ … … 84 84 }}} 85 85 86 This Example1.py macro does not do anything interesting for this problem (it most likely produce an empty plot). You should open it with a text editor, and write a small analysis that selects two muons and reconstructs and plot the recoil Higgs mass.86 This Example1.py macro does not produce anything interesting here (it most likely produce an empty plot). The above command is simply shown as an example for how to run a macro. You should open Example1.py with a text editor, and write a small analysis that first selects events with two muons and then reconstructs and plot the recoil Higgs mass using the formula found in III.1) 87 87 88 88 … … 92 92 You have now produced a Delphes simulated event with the hypothetical CEPC default detector configuration. 93 93 94 1) Can you think of two detector parameters that drive the performance of this measurement?94 1) Can you think of 2 detector parameters that determine and drive the sensitivity of the Higgs recoil measurement in this particular final state? 95 95 96 2) Identify where they are configured in the delphes detector card 96 2) Identify where they are configured in the delphes detector card. 97 97 98 3) Create two new detector configurations by degrad ethese two parameters by a sizable factor.98 3) Create two new detector configurations by degrading these two parameters by a sizable factor. 99 99 100 100 4) Reproduce a Delphes sample with these new configurations and observe the impact on the recoil mass distribution.
