Light Dark Matter through Resonance Scanning
Djuna Croon, Gilly Elor, Rachel Houtz +2
We propose a new out-of-equilibrium production mechanism of light dark matter: resonance scanning. If the dark matter mass evolved in the early Universe, resonant production may ha…
Cosmological phase transitions: is effective field theory just a toy?
Marieke Postma, Graham White
To obtain a first order phase transition requires large new physics corrections to the Standard Model (SM) Higgs potential. This implies that the scale of new physics is relatively…
Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies
N. Aggarwal, O. D. Aguiar, A. Bauswein +22
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
The Electro-Weak Phase Transition at Colliders: Confronting Theoretical Uncertainties and Complementary Channels
Andreas Papaefstathiou, Graham White
We explore and contrast the capabilities of future colliders to probe the nature of the electro-weak phase transition. We focus on the real singlet scalar field extension of the St…
Theoretical uncertainties for cosmological first-order phase transitions
Djuna Croon, Oliver Gould, Philipp Schicho +2
We critically examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as o…
Phase Transitions in an Expanding Universe: Stochastic Gravitational Waves in Standard and Non-Standard Histories
Huai-Ke Guo, Kuver Sinha, Daniel Vagie +1
We undertake a careful analysis of stochastic gravitational wave production from cosmological phase transitions in an expanding universe, studying both a standard radiation as well…
Cosmological Bounds on sub-GeV Dark Vector Bosons from Electromagnetic Energy Injection
John Coffey, Lindsay Forestell, David E. Morrissey +1
New dark vector bosons that couple very feebly to regular matter can be created in the early universe and decay after the onset of big bang nucleosynthesis (BBN) or the formation o…
