Festina-Lente Bound on Higgs Vacuum Structure and Inflation
  The recently suggested Festina-Lente (FL) bound provides a lower bound on the
masses of ${\rm U(1)}$ charged particles in terms of the positive vacuum
energy. Since the charged particle masses in the Standard Model (SM) are
generated by the Higgs mechanism, the FL bound provides a testbed of consistent
Higgs potentials in the current dark energy-dominated universe as well as
during inflation. We study the implications of the FL bound on the UV behavior
of the Higgs potential for a miniscule vacuum energy, as in the current
universe. We also present values of the Hubble parameter and the Higgs vacuum
expectation value allowed by the FL bound during inflation, which implies that
the Higgs cannot stay at the electroweak scale during this epoch.
