Canonical quantization of noncommutative field theory

A simple method to canonically quantize noncommutative field theories is proposed. As a result, the elementary excitations of a $\mathrm{}(2n+1)\mathrm{}$-dimensional scalar field theory are shown to be bilocal objects living in an $\mathrm{}(n+1\mathrm{})\mathrm{}$-dimensional space-time. Feynman rules for their scattering are derived canonically. They agree, upon suitable redefinitions, with the rules obtained via star-product methods. The IR-UV connection is interpreted within this framework.
