H + n-jet Born variables #22

Closed bonanomi closed 3 years ago

bonanomi commented 3 years ago

Set up the framework for measurements of H + n-jet variables.

Most likely we can recreate the new observables directly in RunCoefficients and RunTemplates as we do for pT1j.

To start we could run measurements for:

pT4lj : pT of the 4l system + leading jet pT
m4lj : invariant mass of the 4l system + leading jet mass
pT2j : pT of the sub-leading jet

Expected measurement for pT4lj.

All the variables have been included in the skimmer. For all the cases when the variable would not be defined (eg pT1j or pTHj in 0-jet events) we intend to use a 2D approach for the measurement:

First bin: 0 jet events, inclusive in pT (the second variable is dummy). We measure inclusive xsec and this is what we report in the differential plots
Other bins: >=1 jet events, different bins in pT. For these bins we plot differential dSigma/dOBS2 distributions.

In this way we keep all the events but we separate the two different categories.

LL scans for njet vs pT(H+j) measurement.

Done. All the variables have been implemented in the framework by @AlessandroTarabini .
