Description: Notional amplituhedron visualization. Calculate the scattering amplitude by calculating the volume of the projected hull of selected edges in the n-Simplex Amplituhedron (based on a theory by Nima Arkani-Hamed, with some Mathematica code from J. Bourjaily for the positroid diagram) This diagram is obtained using the author's Mathematica .CDF or .NB code with the following amplituhedron0.m as input to the from ToE_Demonstration.cdf found on http://theoryofeverything.org/MyToE: new := { artPrint=True; scale=0.1; cylR=0.018; range=2.; pt={-0.3, 0.0, 0.6}; favorite=1; showAxes=False; showEdges=True; showPolySurfaces=True; eColorPos=False; dimTrim=5; ds=6; pListName=”First8″; dsName=”nSimplex″; p3D=” 3D”; edgeVals={{Sqrt[11/2], 8}, {Sqrt[9/2 - Sqrt[2]], 4}, {Sqrt[9/2 + Sqrt[2]], 4}}; };new;
