SUMMARY:Searching for new physics during gravitational waves propagati
 on\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Leïla Haegel\, Postd
 octoral fellow at University of Paris & Swiss National Science Foundat
 ion
DESCRIPTION:The direct detection of gravitational waves by the LIGO-Vi
 rgo 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 mor
 phology and the apparent distance of the source. This talk reviews sev
 eral constraints on new physics during the propagation of gravitationa
 l waves\, including massive gravity\, multi messenger signals and deri
 vations in the Standard Model Extension effective field theory.
