Query: Compensation for large tensor modes with iso-curvature perturbations in
  CMB anisotropies   Recently, BICEP2 has reported the large tensor-to-scalar ratio
$r=0.2^{+0.07}_{-0.05}$ from the observation of the cosmic microwave background
(CMB) B-mode at degree-scales. Since tensor modes induce not only CMB B-mode
but also the temperature fluctuations on large scales, to realize the
consistent temperature fluctuations with the Planck result we should consider
suppression of scalar perturbations on corresponding large scales. To realize
such a suppression, we consider anti-correlated iso-curvature perturbations
which could be realized in the simple curvaton model.
