Query: Constructing effective field theories via their harmonics   We consider the construction of operator bases for massless, relativistic
quantum field theories, and show this is equivalent to obtaining the harmonic
modes of a physical manifold (the kinematic Grassmannian), upon which
observables have support. This enables us to recast the approach of effective
field theory (EFT) through the lens of harmonic analysis. We explicitly
construct harmonics corresponding to low mass dimension EFT operators.
