Query: Scalar-tensor correlations and large-scale power suppression   Recent measurements from the BICEP2 cosmic microwave background polarization
experiment indicate the presence of primordial gravitational waves with
surprisingly large amplitude. If these results are confirmed, they point to a
discrepancy with temperature anisotropy power spectrum measurements and suggest
that extensions to the standard cosmological model may be required to resolve
the discrepancy. One intriguing extension is an anticorrelation between tensors
and scalars to naturally suppress the temperature power. Here I examine this
possibility and show that such a suppression is not possible in the presence of
a general form of anticorrelation.
