The `unitarity problem' of Higgs inflation in the light of collapse
  dynamics
  Higgs inflation scenario is one of the most compelling models of inflation at
present time. It not only explains the observed data well, but also provides
means to include the inflaton field within the well understood Standard Model
of particle physics, without invoking any need for its extension. Despite this,
due to the requirement of large non-minimal coupling to the curvature scalar of
the inflaton field, or in this case the Higgs field, this model suffers from a
problem often called as the `unitarity' or the `naturalness' problem. On the
other hand, to address the longstanding `interpretational issue' of quantum to
classical transition of the primordial modes, the collapse dynamics of quantum
mechanics has recently been included into the inflationary mechanism. We show
that inclusion of such collapse mechanism in Higgs inflation helps alleviate
the `unitarity problem' to a great deal.
