BSM with Cosmic Strings: Heavy, up to EeV mass, Unstable Particles
Yann Gouttenoire, Géraldine Servant, Peera Simakachorn
Unstable heavy particles well above the TeV scale are unaccessible experimentally. So far, Big-Bang Nucleosynthesis (BBN) provides the strongest limits on their mass and lifetime,…
Beyond the Standard Models with Cosmic Strings
Yann Gouttenoire, Géraldine Servant, Peera Simakachorn
We examine which information on the early cosmological history can be extracted from the potential measurement by third-generation gravitational-wave observatories of a stochastic…
Relaxion Fluctuations (Self-stopping Relaxion) and Overview of Relaxion Stopping Mechanisms
Nayara Fonseca, Enrico Morgante, Ryosuke Sato +1
In implementations of the electroweak scale cosmological relaxation mechanism proposed so far, the effect of the quantum fluctuations of the homogeneous relaxion field has been ign…
Detecting gravitational waves from cosmological phase transitions with LISA: an update
Chiara Caprini, Mikael Chala, Glauber C. Dorsch +11
We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analy…
Baryogenesis from a dark first-order phase transition
Eleanor Hall, Thomas Konstandin, Robert McGehee +2
We present a very minimal model for baryogenesis by a dark first-order phase transition. It employs a new dark gauge group with two doublet Higgs bosons, two lepton dou…
