AB  - <jats:title>Abstract</jats:title>                  <jats:p>We experimentally investigate the quench dynamics of a spin–orbit–coupled (SOC) Bose–Einstein condensate and its subsequent thermalization. We measure the damping of momentum oscillations and find that the damping rate increases with SOC strength. Comparing the observed damping to theoretical estimates of spin drag in the absence of SOC, we find comparable order-of-magnitude scales, establishing a reference for dissipative processes involving thermal atoms. We emphasize that this comparison provides a baseline rather than a quantitative description of the SOC system. In addition, we directly measure the final temperature after relaxation and observe a decrease with increasing coupling strength. These results provide experimentally constrained benchmarks for finite-temperature theories of non-equilibrium dynamics in SOC quantum gases.</jats:p>
