Hadronization effects and electroweak contributions in DIS one-jettiness
Abstract
We study the structure of leading hadronization effects and the contributions of massive electroweak gauge boson exchange in the τ1 and τ1a 1-Jettiness global event shapes for deep inelastic scattering (DIS). The leading hadronization effects in τ1 acquire a non-trivial dependence on the hard scattering kinematics. This kinematic dependence is explicitly calculable, so that the leading hadronization effects in τ1, τ1a, and DIS thrust are universal and described by the same underlying shape function. The additional calculable kinematic dependence in τ1 provides an independent lever arm for simultaneously constraining hadronization effects in these observables. We present corresponding results at the N3LL+cal O(αs2) level of accuracy. We extend previous results by including the contributions mediated by the exchange of the massive Z and W electroweak gauge bosons for neutral current (NC) and charged current (CC) DIS, respectively, including cal O(αs) QCD corrections to obtain N2LL+cal O(αs) results. We compare theoretical predictions to Pythia simulation and demonstrate the universality of leading hadronization effects across NC and CC DIS processes and a wide range of kinematics relevant to HERA and the EIC.

AB - We study the structure of leading hadronization effects and the contributions of massive electroweak gauge boson exchange in the τ_1 and τ_1a 1-Jettiness global event shapes for deep inelastic scattering (DIS). The leading hadronization effects in τ_1 acquire a non-trivial dependence on the hard scattering kinematics. This kinematic dependence is explicitly calculable, so that the leading hadronization effects in τ_1, τ_1a, and DIS thrust are universal and described by the same underlying shape function. The additional calculable kinematic dependence in τ_1 provides an independent lever arm for simultaneously constraining hadronization effects in these observables. We present corresponding results at the N^3LL+cal O(α_s^2) level of accuracy. We extend previous results by including the contributions mediated by the exchange of the massive Z and W electroweak gauge bosons for neutral current (NC) and charged current (CC) DIS, respectively, including cal O(α_s) QCD corrections to obtain N^2LL+cal O(α_s) results. We compare theoretical predictions to Pythia simulation and demonstrate the universality of leading hadronization effects across NC and CC DIS processes and a wide range of kinematics relevant to HERA and the EIC.
