This quantity can be calculated using the BCFW recursion. In the planar limit of N = 4 supersymmetric Yang-Mills theory, this quantity is equal to the volume of the polytope in which the Grassmanian is positive in momentum twistor space. These values can be calculated from time-ordered correlation functions via the LSZ reduction formula. This quantity for any given order is often found by iteratively calculating the transition operator via the Lippman-Schwinger equation. The first-order version of this quantity is equal to negative 2 m over four pi h-bar squared times the Fourier transform of the potential according to the first-order (*) Born approximation. The imaginary part of this value at an angle of zero, times four pi over k, is equal to sigma-sub-total according to the optical theorem. The magnitude of this quantity, squared, gives the angular dependence of the differential cross section. In the partial wave expansion, this valu

The magnitude of this quantity, squared, gives the angular dependence of the differential cross section. In the partial wave expansion, this value, symbolized f of theta, multiplies the spherical wave term, and in general this value gives the probability of a particle bouncing off a potential and travelling in a given direction. For 10 points, give this value, which is the "height" of the outgoing spherical wave of a scattering event.
