Causal gravitational waves as a probe of free streaming particles and the expansion of the Universe
Anson Hook, Gustavo Marques-Tavares, Davide Racco
The low frequency part of the gravitational wave spectrum generated by local physics, such as a phase transition or parametric resonance, is largely fixed by causality, offering a…
Maximal axion misalignment from a minimal model
Junwu Huang, Amalia Madden, Davide Racco +1
The QCD axion is one of the best motivated dark matter candidates. The misalignment mechanism is well known to produce an abundance of the QCD axion consistent with dark matter for…
Minimal signatures of the Standard Model in non-Gaussianities
Anson Hook, Junwu Huang, Davide Racco
We show that the leading coupling between a shift symmetric inflaton and the Standard Model fermions leads to an induced electroweak symmetry breaking due to particle production du…
Searches for other vacua II: A new Higgstory at the cosmological collider
Anson Hook, Junwu Huang, Davide Racco
The detection of an oscillating pattern in the bispectrum of density perturbations could suggest the existence of a high-energy second minimum in the Higgs potential. If the Higgs…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Implications of the detection of primordial gravitational waves for the Standard Model
G. Franciolini, G. F. Giudice, D. Racco +1
The detection of primordial gravitational waves would not only have extraordinary implications for our understanding of early cosmology, but would also give non-trivial constraints…
