For example, the charged-current contribution to the ?! elastic scattering amplitude
12.
The research program is to understand their deep structure through the study of scattering amplitudes.
13.
Where f is the scattering amplitude.
14.
Progress has been made in calculating background independent scattering amplitudes this way with the use of spin foams.
15.
Correlation functions of local operators living on the boundary of AdS are the natural analogues of scattering amplitudes.
16.
Grassmannians allow the scattering amplitudes of subatomic particles to be calculated via a positive Grassmannian construct called the amplituhedron.
17.
To see how this comes about, consider by contrast how one computes scattering amplitudes without quantum field theory.
18.
When calculating correlation functions instead of scattering amplitudes, there is no past and future and all the lines are internal.
19.
Stripping off the external propagators, that is, removing the factors of } }, gives the invariant scattering amplitude:
20.
This term has had more recent applications in loop quantum gravity in calculating transition amplitudes and background-independent scattering amplitudes.
