Probing Gravitational Dark Matter with Ultra-high Frequency Gravitational Waves
Yong Xu
The evidence for the existence of dark matter (DM) is compelling, yet its nature remains elusive. A minimal scenario involves DM interacting solely through gravity. However, the de…
Modular invariant inflation and reheating
Gui-Jun Ding, Si-Yi Jiang, Yong Xu +1
We use modular symmetry as an organizing principle that attempts to simultaneously address the lepton flavor puzzle, inflation, and post-inflationary reheating. We demonstrate this…
Thermal Gravitational Waves During Reheating
Nicolás Bernal, Yong Xu
In this work, we revisit the generation of stochastic gravitational waves (GWs) from interactions in the thermal plasma. We extend the existing literature by incorporating the rehe…
Ultra-high Frequency Gravitational Waves from Scattering, Bremsstrahlung and Decay during Reheating
Yong Xu
We investigate ultra-high frequency gravitational waves (GWs) from gravitons generated during inflationary reheating. Specifically, we study inflaton scattering with its decay prod…
Probing Reheating with Gravitational Waves from Graviton Bremsstrahlung
Basabendu Barman, Nicolás Bernal, Simon Cléry +3
In this talk, based on arXiv:2301.11345, arXiv:2305.16388, arXiv:2311.12694, we discuss the production of primordial gravitational waves (GW) sourced by graviton bremsstrahlung dur…
Resonant Reheating
Basabendu Barman, Nicolás Bernal, Yong Xu
We investigate a novel reheating scenario proceeding through -channel inflaton annihilation, mediated by a massive scalar. If the inflaton oscillates around the minimum of a…
