Title: Quest for circular polarization of a gravitational wave background and orbits of laser interferometers in space

Abstract

We show that an isotropic component of circular polarization of a stochastic gravitational wave background can be explored by contriving configuration of multiple laser interferometers for correlation analysis. For the proposed BBO mission, the circular polarization degree {pi} can be measured down to {pi}{approx}0.08({omega}{sub GW}/10{sup -15}){sup -1}(SNR/5) with slightly ({approx}10%) sacrificing the detection limit for the total intensity {omega}{sub GW}. This might allow us to detect a signature of parity violation in the very early universe.
