Scattering amplitudes play a central role in our understanding of the fundamental laws of nature. On the one hand they constitute the bridge between theory and experiments, allowing to compute predictions starting from a theoretical model. On the other, they shed light on the underlying properties of quantum field theories. To both ends, analytic results […]

Le CPTGA vous invite à sa 12ème "Journée de Physique Théorique". Le but de ces journées est de permettre des échanges entre physiciens théoriciens de Grenoble/Annecy travaillant dans des domaines très variés. Il est à la fois question de comprendre de la belle science et de découvrir le travail des collègues locaux. Les thèmes de […]
Abstract : The motion of three bodies can be solved perturbatively when a tightly bound inner binary is orbited by a distant perturber on an elliptic orbit. The exchange of […]
Some content and references can be found in the review 1903.06239 or the introduction of 2004.00030.
Warm dark matter (WDM) could explain some small-scale structure observations that have challenged the cold dark matter (CDM) model, as warm particles suppress structure formation due to free streaming effects. […]

A particle physics approach to describing black hole interactions is opening new avenues for understanding gravitational-wave observations. In this talk, we will review this paradigm change showing how general relativity […]
Primordial black holes (PBHs), possibly formed via gravitational collapse of large density perturbations in the very early universe, are one of the earliest proposed and viable dark matter (DM) candidates. […]
