Initial Condition of Relic Gravitational Waves Constrained by LIGO S6 and Multiple Interferometers

Jie-Wen Chen, Yang Zhang, Wen Zhao +1

The relic gravitational wave (RGW) generated during the inflation depends on the initial condition via the amplitude, the spectral index $n_t$ and the running index ${\alpha }_t$. CMB obse…
