Cosmological Aspects of Higgs Vacuum Metastability
read the original abstract
The current central experimental values of the parameters of the Standard Model give rise to a striking conclusion: metastability of the electroweak vacuum is favoured over absolute stability. A metastable vacuum for the Higgs boson implies that it is possible, and in fact inevitable, that a vacuum decay takes place with catastrophic consequences for the Universe. The metastability of the Higgs vacuum is especially significant for cosmology, because there are many mechanisms that could have triggered the decay of the electroweak vacuum in the early Universe. We present a comprehensive review of the implications from Higgs vacuum metastability for cosmology along with a pedagogical discussion of the related theoretical topics, including renormalization group improvement, quantum field theory in curved spacetime and vacuum decay in field theory.

The fermion sector of the SMEFT from asymptotically safe gravity
In a toy model of one quark generation, asymptotically safe gravity predicts four-fermion SMEFT coefficients are either Planck-scale suppressed or zero, with exceptions only at very large gravitational coupling.

Gravitational waves from super-Hubble bubbles
Super-Hubble bubbles nucleated in inflation and colliding soon after can shift GW peak frequency down and boost amplitude enough to enter LIGO/LISA/PTA bands.

Dark Energy Bubble as Dynamical Dark Energy: Properties and CMB Constraints
A late-time bubble of lower dark energy density can mimic DESI BAO features, but CMB dipole, kSZ, and sound-horizon constraints exclude the required parameters.

Evidence for renormalized instantons in real-time simulations of vacuum decay
Ensemble-averaged bubble profiles and decay rates from zero-temperature lattice simulations match Coleman instantons computed in a one-parameter renormalized effective potential, not the bare potential.

Scalar field effective potentials in de Sitter spacetime
Explicit one-loop computation shows the constraint effective potential for scalars in de Sitter is free of infrared problems and supports its use in stochastic Starobinsky-Yokoyama inflation.

Study of Higgs boson pair production in the $HH \rightarrow b \overline{b} \gamma \gamma$ final state with 308 fb$^{-1}$ of data collected at $\sqrt{s} =$ 13 TeV and 13.6 TeV by the ATLAS experiment
Updated ATLAS search for HH → bbγγ with 308 fb⁻¹ yields observed μ_HH = 0.9^{+1.4}_{-1.1}, 95% CL limit μ_HH < 3.7, and κ_λ in [-1.6, 6.6].
