+** Preliminary Results **
+  * R with ATLAS Drell-Yan analysis 8TeV 20.3/fb: [[https://www.dropbox.com/s/qfh22icw2andu0t/R_ATLAS8TeV.pdf|Plot]]
+  * R with ATLAS Drell-Yan analysis 13 TeV 36/fb: [[https://www.dropbox.com/s/be23d9n6esc3wr9/ATLAS_13tev.pdf|Plot]]
+  * Examples of R with some benchmark EFT coefficients: [[https://www.dropbox.com/s/mdhjr5gyomvvxfj/R_examples.pdf|Plot]]
+  * On uncertainties, looking at the ratio of PDFs between 13 and 8 TeV: http://www.hep.ph.ic.ac.uk/~wstirlin/plots/plots.html we expect signal statistics to increase by at least a factor of 2 per fb-1 below 1TeV and up to a factor of 3 at 1.5TeV. For 8TeV ATLAS measurement stat and syst uncertanties are compatible up to ~300-380GeV. Increasing the data to full Run 2 would make stat and syst compatible up to around 500GeV using the current binning. We would expect another factor of 2 of stat uncertainties decrease for full Run 3 with ATLAS/CMS combination.
