Anisotropic inflation from supergravity

It is known that there exists a non-trivial coupling between scalar fields and kinetic terms of gauge fields. Based on this fact, we found a novel inflationary scenario, the so-called anisotropic inflation. We succeeded in clarifying the existence of the statistical anisotropy in the cosmic microwave temperature fluctuations and the cross correlation between the temperature fluctuations and polarizations. Although we could not prove our model using cosmological data due to the delay of the data release by the Planck team, I am sure we opened a new window for exploring fundamental theory of nature through the cosmological data stemmed from the early universe.
