Abstract
We study the matter one-loop quantum corrections to the gravitational sector in a gravity theory coupled with a nonlocal scalar field. We find that non-renormalizable divergences disappear when the propagator of the scalar field approaches to a non-zero constant at high momentum, while the vacuum energy is still divergent. We also comment on non-local modification of fermion, gauge field and graviton.
