  1. 2D limits contours Benoit Clément – IReS Strasbourg Single top meeting

  2. Previous results JLIP/Lh result (370 pb-1) : Expected Observed But… NN analysis also had 2D limit contours :

  3. Combining LHs 4 filters : s/tt, s/Wjj, t/tt, t/Wjj -> needs to recombine tt and Wjj filters in one single variable. Reinhard’s solution : use a LH to rebin tt/Wjj 2D histogram What I did : Just use the product of the two LH variables. Less sensitive to statistical fluctuation in low populated bins. Derive s-channel vs t-channel 2D LH histograms

  4. 2D contour

  5. Inclusive limits SM independent Expected Observed New combined s+t : < 4.8 pb
