Bjorken x weighted energy-energy correlators from the target fragmentation region to the current fragmentation region

Abstract

We present the complete spectrum for the Bjorken x weighted energy-energy correlation in the deep inelastic scattering (DIS) process, from the target fragmentation region to the current fragmentation region, in the Breit frame. The corresponding collinear and transverse momentum-dependent logarithms are resummed to all orders with the accuracy of NLL and N3LL, respectively. The results in the full region are matched with an O(αs2) fixed-order calculation. The final numerical predictions are presented for both Electron-Ion Collider and Continuous Electron Beam Accelerator Facility kinematics. Published by the American Physical Society 2024
