  1. Phase-space sectors for ordered momentum mappings in local subtraction up to N$^3$LO

    hep-ph 2025-07 conditional novelty 7.0 of 10

    A sector decomposition of phase space assigns ordered momentum mappings to antenna functions without partial fractioning, enabling simpler N3LO infrared subtraction.

  2. Sudakov evolution without unitarity

    hep-ph 2025-06 accept novelty 7.0 of 10

    Sunshine removes Sudakov factors from parton-shower sampling by keeping every intermediate state, giving direct tree-level expansions and enabling tests of matrix-element corrections.

  3. Timelike showers with jet recoils

    hep-ph 2025-12 conditional novelty 6.0 of 10

    A 'jet recoil' scheme assigning momentum-balance recoil to clusters of partons chosen by angular ordering brings kt-ordered dipole parton showers to next-to-leading-logarithmic accuracy, shown by fixed-order and resum...
