Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2028.

Abstract

Scattering amplitudes are central objects in quantum field theory, but standard methods for computing them often produce expressions that are much more complicated than the final answer. The amplituhedron was introduced to explain this phenomenon geometrically: different recursive expansions should correspond to different triangulations of a single positive geometric object, with spurious singularities canceling…
