We introduce a method to reconstruct the kinematics of neutral-current deep inelastic scattering (DIS) using a deep neural network (DNN). Unlike traditional methods, it exploits the full kinematic information of both the scattered electron and the hadronic-final state, and it accounts for QED radiation by identifying events with radiated photons and event-level momentum imbalance. The method is studied with simulated events at HERA and the future Electron-Ion Collider (EIC). We show that the… 


On the Kinematic Reconstruction of Deep Inelastic Scattering at HERA: the $\Sigma$ Method
We review and compare the reconstruction methods of the inclusive deep inelastic scattering variables used at HERA. We introduce a new prescription, the $\Sigma$ method, which allows to measure the
Measurement of lepton-jet correlation in deep-inelastic scattering with the H1 detector using machine learning for unfolding
The first measurement of lepton-jet momentum imbalance and azimuthal correlation in leptonproton scattering at high momentum transfer is presented. These data, taken with the H1 detector at HERA, are
Measurement of theF2 structure function in deep inelastice+p scattering using 1994 data from the ZEUS detector at HERA
We present measurements of the structure functionF2 ine+p scattering at HERA in the range 3.5 GeV2<Q2<5000 GeV2. A new reconstruction method has allowed a significant improvement in the resolution of

Combined QED and QCD radiative effects in deep inelastic lepton-proton scattering: the Monte Carlo generator DJANGO6
We describe the event generator DJANGO6, which simulates deep inelastic lepton-proton scattering including both QED and QCD radiative effects. DJANGO6 is an interface of the programs HERACLES 4.4 and
