Here I look at detector level dijets which do not have a matching particle level dijet ...

I have removed the production2009_200Gev_Lo runs and implemented the high jet pt cuts as described here.

Figure 1: This figure shows the detector level - particle level jet eta and phi as well as delta R (sqrt(deltaEta^2 + deltaPhi^2). The red curves show the same-side jets and the blue curves show the away-side jets. The condition for dijet matching between detector and particle level is that both jets which make up the dijet must have a delta R < 0.5 .

Figure 2: This figure shows the pt, eta, detector eta, and phi spectra of jets which fail the delta R < 0.5 cut. The red curve is same-side jets and the blue curve is away-side jets.

Figure 3: This figure shows jet vs jet correlation plots for detector level dijets which do not have a matching particle level dijet. The x-axis quantity is always from the hi pt jet and the y-axis quantity is always from the lo pt jet.

Figure 4: This figure shows the detector level dijet mass spectrum before the detector-particle level matching was imposed (blue curve) and the detector level dijet mass spectrum of dijets which fail the detector-particle level matching. The bottom plot is the same histogram binned corser in mass. The bin edges are 7, 10, 13, 16, 19, 23, 28, 34, 41, 49, 58, 69, 82, 100, 120.
