Can one tell Einstein's unimodular theory from Einstein's general relativity?

Abstract

The so called unimodular theory of gravitation is compared with general relativity in the quadratic (Fierz-Pauli) regime, using a quite broad framework, and it is argued that quantum effects allow in principle to discriminate between both theories.
