Query: M5-Brane Amplitudes   The dynamics of a probe M5-brane, embedded as a hypersurface in
eleven-dimensional Minkowski spacetime, is described by a six-dimensional
world-volume theory. This theory has a variety of interesting symmetries some
of which are obscure in the Lagrangian formulation of the theory. However, as
summarized in this review, an alternative approach is to construct all of its
on-shell tree-level scattering amplitudes. This enables understanding all of
the symmetries in a satisfying way. This work is dedicated to the memory of
Peter Freund.
