      abstract     = {We argue that the Standard Model (SM) in the Higgs phase
                      does not suffer from a 'hierarchy problem' and that
                      similarly the 'cosmological constant problem' resolves
                      itself if we understand the SM as a low energy effective
                      theory emerging from a cutoff-medium at the Planck scale. We
                      actually take serious Veltman's 'The Infrared - Ultraviolet
                      Connection' addressing the issue of quadratic divergences
                      and the related huge radiative correction predicted by the
                      SM in the relationship between the bare and the renormalized
                      theory, usually called 'the hierarchy problem' and claimed
                      that this has to be cured. We discuss these issues under the
                      condition of a stable Higgs vacuum, which allows to extend
                      the SM up to the Planck cutoff. The bare Higgs boson mass
                      then changes sign below the Planck scale, such that the SM
                      in the early universe is in the symmetric phase. The cutoff
                      enhanced Higgs mass term as well as the quartically enhanced
                      cosmological constant term provide a large positive dark
                      energy which triggers the inflation of the early universe.
                      Reheating follows via the decays of the four unstable heavy
                      Higgs particles, predominantly into top-antitop pairs, which
                      at this stage are still massless. Preheating is suppressed
                      in SM inflation since in the symmetric phase bosonic decay
                      channels are absent at tree level. The coefficients of the
                      shift between bare and renormalized Higgs mass as well as of
                      the shift between bare and renormalized vacuum energy
                      density exhibit close-by zeros at about $7.7 \times 10^{14}$
                      GeV and $3.1 \times 10^{15}$ GeV, respectively. The zero of
                      of the Higgs mass counter term triggers the electroweak
                      phase transition from the low energy Higgs phase and to the
                      symmetric phase above the transition point. The scenario
                      highly favors to understand the SM and its main properties
                      as a natural structure emerging at long distance.},
