Using q-theory, we show that the electroweak crossover can generate a remnant vacuum energy density Λ∼E8ew/E4Planck, with effective electroweak energy scale Eew∼103  GeV and reduced Planck-energy scale EPlanck∼1018  GeV. The obtained expression for the effective cosmological constant Λ 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).
