When the HL-LHC is blind, LISA is deaf (but not vice versa): 2HDM collider-cosmology synergies
Stefano Moretti, André Pousette, Carlo Tasillo
Extensions of the Standard Model scalar sector can render the electroweak phase transition first-order and thereby provide the departure from thermal equilibrium required for elect…

Tuning the violins: dark sector phase transition models for the PTA signal
Torsten Bringmann, Thomas Konstandin, Jonas Matuszak +2
First-order phase transitions in a dark sector have been invoked as an intriguing possibility to explain the observed stochastic gravitational wave background at nanohertz frequenc…

Sub-GeV dark matter and nano-Hertz gravitational waves from a classically conformal dark sector
Sowmiya Balan, Torsten Bringmann, Felix Kahlhoefer +2
Strong first-order phase transitions in a dark sector offer a compelling explanation for the stochastic gravitational wave background in the nano-Hertz range recently detected by p…
