Using q-theory, we show that the electroweak crossover can generate a remnant vacuum energy density {lambda}{approx}E{sub ew}{sup 8}/E{sub Planck}{sup 4}, with effective electroweak energy scale E{sub ew}{approx}10{sup 3} GeV and reduced Planck-energy scale E{sub Planck}{approx}10{sup 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)
