DESCRIPTION:Speakers: Mawande Lushozi (University of Cape Town)\nThe next 
 decade of heavy-ion phenomenology will be significantly shaped by the expa
 nsion of experimental reach into far forward kinematics. Upcoming detector
  upgrades\, such as the ALICE FoCal programme and STAR forward calorimetry
 \, require robust theoretical baselines to interpret baryon stopping in re
 gions where standard boost-invariant models fail. We present a fully 3+1D 
 classical transport framework for pre-equilibrium baryon number deposition
  within the Color Glass Condensate framework. The collision is modelled in
  the target rest frame as an ultra-relativistic saturated gluon sheet swee
 ping through a static distribution of collisionless classical coloured par
 ticles (Wong quarks). Averaging over the McLerran-Venugopalan ensemble yie
 lds the saturation-driven transverse momentum kicks imparted to the target
  degrees of freedom. This formulation provides analytic and semi-analytic 
 solutions for the phase-space distribution\, baryon current\, and proper b
 aryon density. By extending previous one-dimensional shockwave models to a
  realistic 3+1D geometry incorporating Woods-Saxon profiles\, we explicitl
 y quantify the competition between longitudinal compression and transverse
  expansion induced by momentum broadening. We derive a closed analytic exp
 ression for the transported baryon rapidity distribution\, peaking at $y \
 \simeq \\frac{1}{2}\\ln(Q_s^2/m_q^2)$. These results establish a mathemati
 cally controlled initial state baseline for forward-rapidity hydrodynamics
 \, offering testable quantitative predictions for high-density QCD matter\
