<div class=""><font size="3" class="">Title: Neutron structure from deuteron DIS with spectator proton tagging<br class="">
<br class="">
Abstract: Electron-deuteron deep inelastic scattering with detection of a spectator proton enables extraction of neutron partonic structure with maximum control of nuclear effects. We outline the theoretical formalism to describe these reactions, based on
methods of light-front nuclear structure. We show how low-energy nuclear structure enters into tagged observables (cross sections, asymmetries) and how the dependence on the kinematics of the tagged spectator enters. As an application, we focus on the tagged
longitudinal double spin asymmetry. We consider two possible denominators in the asymmetry: i) with the unpolarized deuteron (-1,0,+1 states), ii) with only maximum (-1,+1) states; we demonstrate the latter asymmetry results in smaller nuclear depolarization
effects at small spectator momenta. The method of pole extrapolation of these asymmetries can be used to extract g_1n of the free neutron. This would be possible over a wide kinematic range at a future EIC with polarized deuteron beams and forward detectors.
In the last part of the talk, we discuss possible extensions with deuteron tensor polarization, A=3 nuclei and the effects of nuclear final-state interactions.</font><br class="">
