The probability amplitude? for a process of scattering of fundamental particles or fundamental strings off each other. The collection of scattering amplitudes forms the S-matrix.

In super Yang-Mills theory
In super Yang-Mills theory (and there in particular in the planar limit of N=4 D=4 super Yang-Mills theory) scattering amplitudes enjoy special symmetry properties, some of which can be used to extract information about scattering amplitudes in non-supersymmetric theories:
