Understand

A class of nonlocal Lorentzian quantum field theories is introduced in arXiv:1502.01655 and arXiv:1411.6513, where the d'Alembertian operator $\Box$ is replaced by a non-analytic function of the d'Alembertian, $f(\Box)$.

This is inspired by the Causal Set program where such an evolution arises as the continuum limit of a wave equation on causal sets.
The spectrum of these theories contains a continuum of massive excitations.
This is perhaps the most important feature which leads to distinct/interesting phenomenology.
