This talk presents a cutting-edge analysis of the 1-jettiness event shape in deep inelastic scattering (DIS), utilizing Soft-Collinear Effective Theory. The study achieves high precision at N³LL + O(αₛ²) accuracy, incorporating full fixed-order matching along with nonperturbative corrections. It represents one of the most accurate event-shape predictions in DIS to date and supports precise determinations of the strong coupling constant αₛ and the universal nonperturbative parameter Ω₁. The approach is directly relevant to data from both HERA and the future Electron-Ion Collider (EIC).
