-    * LH Accord for scale variations? [discussion on: **Thu June 8th,  09h00-10h30**]
+===== Notes from the discussion in LH =====
+Slides: [[:2017:scales_pires.pdf | scale choices]]
+   * decompose inclusive PT distributions to the sum of PT1, PT2, PT3, PT4+ (possible follow-up from the planned experimental measurements), (award is: bet of free coffee from Daniel Maitre)
+   * what about other scales HT/2
+   * cone size dependences
+   * Gregors Soyez suggestion for DR-informed scale varition for large and small anglularly separated jets (?) [to be further clarified]
+===For more details, see the notes for the Fixed Order vs ME+PS comparisons for inclusive jets ====
+====Scale choices in ratios====
+   *understand degree of scale cancellations in ratios of cross sections by comparing NLO predictions with corresponding NNLO ones, i.e. W+>=1 jet/Z+>=1 jet, H+>=1 jet/Z+>=1 jet at NLO and at NNLO, using same central scale and variations about that scale
