On quantifying and resolving the BICEP2/Planck tension over gravitational waves

Kendrick M. Smith, Cora Dvorkin, Latham Boyle +4

The recent BICEP2 measurement of primordial gravity waves (r = 0.2^{+0.07}_{-0.05}) appears to be in tension with the upper limit from WMAP (r<0.13 at 95% CL) and Planck (r<0.11 at…
