Small non-Gaussianity and dipole asymmetry in the CMB
  In this paper we provide a prescription for obtaining a small non-Gaussianity
and the observed dipole asymmetry in the cosmic microwave background radiation.
The observations inevitably lead to multi-field inflationary dynamics, where
each field can create positive or negative large non-Gaussianity, resulting a
fine cancellation but with an observable imprint on the hemispherical
asymmetry. We discuss this possibility within a simple slow-roll scenario and
find that it is hard to explain the observed dipole asymmetry. We briefly
discuss some speculative scenarios where one can explain dipole asymmetry.
