 +Extract R(m_ll) from these searches: 
 +  * ATLAS 13 TeV bump search with 139/fb: https://​arxiv.org/​abs/​1903.06248 (https://​www.hepdata.net/​record/​ins1725190) (36/fb here: https://​arxiv.org/​abs/​1707.02424 - https://​www.hepdata.net/​record/​79077) 
 +  * ATLAS 8 TeV SM Drell-Yan measurement:​ https://​arxiv.org/​abs/​1606.01736 (http://​hepdata.cedar.ac.uk/​h8test/​view/​ins1467454) 
 +  * CMS 8 TeV SM Drell-Yan measurement:​ https://​arxiv.org/​abs/​1412.1115 (http://​hepdata.cedar.ac.uk/​view/​ins1332509) 
 + 
 +** 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 uncertaintieslooking 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.
