Asymmetric jet clustering in deep-inelastic scattering

Abstract

We propose a new jet algorithm for deep-inelastic scattering (DIS) that accounts for the target-current asymmetry in the Breit frame. The Centauro algorithm is longitudinally invariant and can cluster jets with near-to Born kinematics, which enables novel studies of transverse-momentum-dependent observables. Furthermore, we show that spherically-invariant algorithms in the Breit frame give access to low-energy jets from current fragmentation. We perform a calculation of the energy spectrum of Centauro jets at next-to-leading logarithmic accuracy and compare to pythia simulations. We furthermore propose novel studies in unpolarized, polarized, and nuclear DIS at the future Electron-Ion Collider.
