LH Accord for scale variations

People: João Pires, Kostas Theofilatos, Joey Huston … (add your name if you are interested)

Notes from the discussion in LH

Slides: 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
