abstract

Motivated by recently observed tension between $O\left(\alpha_s^2\right)$ calculations of very large transverse momentum dependence in both semi-inclusive deep inelastic scattering and Drell-Yan scattering, we repeat the details of the calculation through $O\left(\alpha_s^2\right)$ transversely differential cross section. The results confirm earlier calculations, and provide further support to the observation that tension exists with current parton distribution and fragmentation functions.

  1. Dihadron Angular Correlations in the $e^+e^-$ Collision

    hep-ph 2025-06 conditional novelty 7.0 of 10

    The paper derives the first complete O(alpha_s^2) analytic QCD corrections to the dihadron angular separation distribution in e+e- annihilation, with verified cancellation of infrared poles.

  2. Angular phase-space integrals with four denominators through Mellin--Barnes

    hep-ph 2025-08 conditional novelty 6.0 of 10

    Four-denominator angular phase-space integrals are computed to O(epsilon^0) in dimensional regularization and expressed in GPLs for massless and massive momenta.
