Higgs-inflaton coupling from reheating and the metastable Universe
  Current Higgs boson and top quark data favor metastability of our vacuum
which raises questions as to why the Universe has chosen an energetically
disfavored state and remained there during inflation. In this Letter, we point
out that these problems can be solved by a Higgs-inflaton coupling which
appears in realistic models of inflation. Since an inflaton must couple to the
Standard Model particles either directly or indirectly, such a coupling is
generated radiatively, even if absent at tree level. As a result, the dynamics
of the Higgs field can change dramatically.
