abstract
We study the generation of intergalactic magnetic fields in two models for first-order phase transitions in the early Universe that have been studied previously in connection with the generation of gravitational waves (GWs): the Standard Model supplemented by an $|H|^6$ operator (SM+$H^6$) and a classically scale-invariant model with an extra gauged U(1) $B - L$ symmetry (SM$_{B-L}$). We consider contributions to magnetic fields generated by bubble collisions and by turbulence in the primordial plasma, and we consider the hypotheses that helicity is seeded in the gauge field or kinetically. We study the conditions under which the intergalactic magnetic fields generated may be larger than the lower bounds from blazar observations, and correlate them with the observability of GWs and possible collider signatures. In the SM+$H^6$ model bubble collisions alone cannot yield large enough magnetic fields, whereas turbulence may do so. In the SM$_{B-L}$ model bubble collisions and turbulence may both yield magnetic fields above the blazar bound unless the B$-$L gauge boson is very heavy. In both models there may be observable GW and collider signatures if sufficiently large magnetic fields are generated.

Can the universe be matter-dominated after a supercooled first-order phase transition?
After a supercooled first-order phase transition, the scalar field's equation of state is set by the bubble-wall Lorentz factor γ*, and matter domination is delayed until a/a* ≃ γ* in the free-streaming limit.

Hot news on the phase structure of the SMEFT
A full O(g^4) dimensional reduction of the dimension-six SMEFT shows that the top-Higgs operator O_tphi can trigger a first-order electroweak phase transition with zero (phi-dagger phi)^3 coupling at zero temperature.

Complementarity of gravitational wave analyses and di-Higgs production in the exploration of the Electroweak Phase Transition dynamics in the RxSM
In the real singlet extension of the SM, strong first-order electroweak phase transitions split into singlet-driven transitions (loud in gravitational waves, quiet at colliders) and doublet-driven transitions (visible...

Investigating a strong first-order electroweak phase transition in the RxSM at future linear $e^+e^-$ colliders and LISA
In the RxSM, singlet-driven SFOEWPTs yield strong LISA GW signals with SM-like Higgs couplings, while doublet-driven ones yield large κ_λ deviations visible at ILC1000 but weak GWs.

Light nuclei under magnetic field and the lithium problem
Magnetic fields linearly change the exponential decay rate of light-nucleus wave functions, which the authors argue could enhance low-energy fusion reactions and, at implausibly high field strengths, affect the Big Ba...
