BICEP2. Results are reported from the BICEP2 experiment, a Cosmic Microwave Background (CMB) polarimeter specifically designed to search for the signal of inflationary gravitational waves in the B-mode power spectrum around angular multipole ~ 80. BICEP2 observed from the South Pole for three seasons from 2010 to 2012. An excess of B-mode power over the base lensed-LambdaCDM expectation is found in the range 30 < multipole < 150, inconsistent with the null hypothesis at a significance of > 5 sigma. The observed B-mode power spectrum is well-fit by a lensed-LambdaCDM + tensor theoretical model with tensor/scalar ratio r = 0.20 +0.07,-0.05, with r = 0 disfavoured at 7.0 sigma.
