Self-interacting Spin-2 Dark Matter
Xiaoyong Chu, Camilo Garcia-Cely
Recent developments in bigravity allow one to construct consistent theories of interacting spin-2 particles that are free of ghosts. In this framework, we propose an elementary spi…
Dark matter indirect signals with long-lived mediators
Xiaoyong Chu, Suchita Kulkarni, Pierre Salati
Dark matter particles could annihilate into light and metastable mediators subsequently decaying far away from where they are produced. In this scenario, the indirect signatures of…
Self-interacting dark matter as a solution to the problems in small-scale structures
Camilo Garcia-Cely, Xiaoyong Chu
Dark matter self-interactions are a well-motivated solution to the core-vs.-cusp and the too-big-to-fail problems. They are commonly induced by means of a light mediator, that is a…
Simply split SIMPs
Nicolás Bernal, Xiaoyong Chu, Josef Pradler
Dark Matter which interacts strongly with itself, but only feebly with the Standard Model is a possibility that has been entertained to solve apparent small-scale structure problem…
