Narrative:
Descending on the BLUZZ1 RNAV arrival approx 10MN west of axxel encountered wake turbulence (wing tip) off a widebody transport ahead of us on the arrival. Aircraft rolled 20 deg right then 40 degs left; autopilot disconnected itself. Manually lowered nose recovered wings level and expedited descent to exit vorticies. Winds were 260/50 at altitude pretty much on the nose. Our aircraft weighed approx 305K. Visually appeared other aircraft was 10-15 miles ahead on the approach. Appeared to be a one-off incident. [In many] years of flying arrivals [I] have never seen a wake turbulence incident of this magnitude; all factors and rules seemed to have been complied with but still experienced vorticies and aircraft upset. [Suggest] greater spacing.
