We consider the back-to-back region in the energy--energy correlation in e^+e^- collisions. We present the explicit expression of the O(as^2) logarithmically enhanced contributions up to next-to-next-to-leading logarithmic accuracy. We study the impact of the results in a detailed comparison with precise LEP and SLC data. We find that, when hadronization effects are taken into account as is customarily done in QCD analysis in e^+e^- annihilations, the extracted value of as(M_Z) is in good agreement with the current world average.

  1. Precision $e^+e^-$ Hemisphere Masses in the Dijet Region with Power Corrections

    hep-ph 2025-06 conditional novelty 8.0 of 10

    N3LL' resummation for heavy jet and dihemisphere masses in the dijet region, with a new claim that heavy jet mass moments require an extra non-perturbative parameter at order 1/Q.

  2. Benchmarking the Nearside Energy-Energy Correlators with Mellin Transform

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A Mellin-transform framework with one fitted transition scale Λ describes nearside EECs in e+e− annihilation at NNLO+NNLL accuracy across ALEPH and earlier data.

  3. HDSense: An efficient method for ranking observable sensitivity

    hep-ph 2026-02 conditional novelty 6.0 of 10

    HDSense ranks observable subsets by adding per-observable Fisher information and penalizing overlap, picking near-optimal sets for Pythia hadronization parameters in tested cases.

  4. Energy correlators in four-dimensional gravity

    hep-th 2025-12 conditional novelty 6.0 of 10

    Gravitational energy correlators in four dimensions are computed at one loop, shown to be infrared-finite, and resummed in the back-to-back limit by soft-graviton exponentiation.

  5. Factorization and Resummation for the Nearside Energy-Energy Correlators

    hep-ph 2025-07 conditional novelty 6.0 of 10

    A new all-order resummation formula in Fourier b_T-space for the nearside energy-energy correlator, derived from di-hadron fragmentation functions, matches fixed-order calculations and predicts a small-angle turnover.

  6. Factorization of the Energy-Energy Correlation in the two-jet limit in the massive case

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Authors introduce a partial two-jet event fraction for massive-quark EEC and an improved factorization scheme with χ-dependent coefficient function.

  7. Energy Correlators Resolving Proton Spin

    hep-ph 2025-09 unverdicted novelty 5.0 of 10

    The work establishes a correspondence between spin-dependent energy correlators and polarized TMDs/NECs using SCET, yielding N3LL/N2LL predictions for correlation patterns in current and target fragmentation regions.
