Environment - Non Weather Related; Procedure
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.
[Report narrative contained no additional information].
Widebody transport flight crew reported the aircraft rolled up to 40 degrees after encountering wake turbulence on arrival to MEM in trail of another wide body aircraft.
