Who cares about physics today? A marketing strategy for the survival of fundamental science and the benefit of society
Umberto Cannella
It would seem that the present dry economic times impose a very precise focus for science in general and physics in particular: research, possibly of applied type. However in doing…
Effective Field Theory Methods in Gravitational Physics and Tests of Gravity
Umberto Cannella
In this PhD thesis I make use of the "Effective Field Theory of Gravity for Extended Objects" by Goldberger and Rothstein in order to investigate theories of gravity and to take a…
Extracting the three- and four-graviton vertices from binary pulsars and coalescing binaries
Umberto Cannella, Stefano Foffa, Michele Maggiore +2
Using a formulation of the post-Newtonian expansion in terms of Feynman graphs, we discuss how various tests of General Relativity (GR) can be translated into measurement of the th…
Classical energy momentum tensor renormalisation via effective field theory methods
Umberto Cannella, Riccardo Sturani
We apply the Effective Field Theory approach to General Relativity, introduced by Goldberger and Rothstein, to study point-like and string-like sources in the context of scalar-ten…
