Probing the neutron structure via polarized $^{3}$He with double-tagging at EIC*

In several electron scattering experiments, polarized $^{3}$He plays a role of an effective polarized neutron target and enable us to study the spin-dependent structure of a neutron. With simultaneous detection of two spectator protons (double-tagging) it is possible to perform the spin-dependence study with minimization of nuclear effects. Here we present a study of the electron scattering from polarized $^{3}$He with double tagging at future Electron-Ion Collider (EIC) at two representative kinematics in terms of energies of colliding electron and ion beams with focus on two different regimes of $^3$He breakup: short-range correlations (SRC) and 3-body-breakup in the mean field (3BBU-MF).
