Description
As a first step towards precise and differential predictions, we calculate the cross section for e+e− → 2 jets differential in the angularities eα and eβ. The logarithms of eα and eβ are jointly resummed to NNLL logarithmic accuracy, using the SCET+ framework we developed, and are matched with the NLO fixed-order prediction. We calculate the necessary ingredients, discuss scales and uncertainties, and obtain numerical predictions that we compare to Pythia. Predictions for the cross section differential in the ratio eα/eβ are also obtained. Furthermore, our results are validated at order αs2 by comparing to Event2.
