UV/IR symmetries of the S-matrix and RG flow

The low energy S-matrix which describes non-relativistic two-body
scattering arising from finite-range forces has UV/IR symmetries
that are hidden in the corresponding effective field theory (EFT) action.
It is shown that the S-matrix symmetries are manifest as geometric properties
of the RG flow of the coefficients of local operators in the EFT action.
