abstract

We extend the ARES method for next-to-next-to-leading-logarithmic (NNLL) QCD resummations to three-jet event shapes in $e^+ e^-$ collisions in the near-to-planar limit. In particular, we define a NNLL radiator for three hard emitters, and discuss new features of NNLL corrections arising specifically in this case. As an example, we present predictions for the $D$-parameter, matched to exact NLO. After inclusion of hadronisation corrections in the dispersive approach, we compare our predictions with LEP1 data.

  1. The Three-Point Energy Correlator in the Coplanar Limit

    hep-ph 2024-11 conditional novelty 7.0 of 10

    A new tau_p projection makes the coplanar limit of the three-point energy correlator a TMD-factorized trijet observable, resummed to N3LL, the first trijet event shape at this order.

  2. The Quark Jet Function for $k_T$-like Variables in NNLO QCD

    hep-ph 2025-08 conditional novelty 6.0 of 10

    The authors compute the quark jet function at next-to-next-to-leading order in QCD for a class of kT-like resolution variables, giving explicit numerical coefficients for a y23 variant in the E-scheme and WTA scheme.
