Abstract
Gauge theories coupled with the gravitational field and external matte r fields are considered and Notherian techniques are used to build the canonical conserved quantities. Their superpotentials are found and t he relation between the canonical stress tensor and the Hilbert tensor is determined. The case of Yang-Mills theories coupled with gravity a nd scalar matter fields is considered in detail and it is shown that i n this case the canonical stress tensor and the Hilbert tensor coincid e.
