On the Charged and CP-violating Kink Solutions in the Two Higgs Doublet Model / Law, Kai Hong (Manchester U.) ; Pilaftsis, Apostolos (Manchester U. ; CERN)
Minimal extensions of the Standard Model (SM), such as the so-called Two Higgs Doublet Model (2HDM), can possess several accidental discrete symmetries whose spontaneous breakdown in the early universe usually lead to the formation of domain walls. [...]

Dark Matter Freeze-In with a Heavy Mediator: Beyond the EFT Approach / Frangipane, Evan (UC, Santa Cruz) ; Gori, Stefania (UC, Santa Cruz) ; Shakya, Bibhushan (DESY ; CERN)
We study dark matter freeze-in scenarios where the mass of the mediator particle that couples dark matter to the Standard Model is larger than the reheat temperature, TRH, in the early Universe. [...]
