Vacuum energy density kicked by the electroweak crossover
read the original abstract
Using q-theory, we show that the electroweak crossover can generate a remnant vacuum energy density \Lambda \sim E_{ew}^8 / E_{planck}^4, with effective electroweak energy scale E_{ew} \sim 10^{3} GeV and reduced Planck-energy scale E_{planck} \sim 10^{18} GeV. The obtained expression for the effective cosmological constant \Lambda may be a crucial input for the suggested solution by Arkani-Hamed et al. of the triple cosmic coincidence puzzle (why the orders of magnitude of the energy densities of vacuum, matter, and radiation are approximately the same in the present Universe).

Topolons: Stable Particle-Like Remnants of Collapsed Vacuum Bubbles
Vacuum bubbles carrying quantized monopole flux on their walls collapse to stable particle-like remnants whose mass is fixed by the wall scale and conserved flux.
