Searching for new physics during gravitational waves propagation
Time: 2:30 pm
Place: online
Speaker: Leïla Haegel, Postdoctoral fellow at University of Paris & Swiss National Science Foundation
Abstract: The direct detection of gravitational waves by the LIGO-Virgo collaboration in 2015 opened a new channel to probe the existence of new physics. The existence of new fields are predicted in several alternative theories of gravitation, including low-energy effects of a possible quantum theory of gravity. The presence of such fields can induce a dispersion of the gravitational radiation, impacting its morphology and the apparent distance of the source. This talk reviews several constraints on new physics during the propagation of gravitational waves, including massive gravity, multi messenger signals and derivations in the Standard Model Extension effective field theory.
