The Advanced LIGO detectors have a proposed distance reach of ∼ 445M pc. for binary neutron star (BNS) events and are expected to detect few events of BNS inspiral per month. In this work, we propose a new hybrid detection statistic to address the coherent multi-detector search of gravitational wave from compact binary coalescences with Neutron stars and Black Holes. The performance of the hybrid statistic is compared with that of the generic coherent multi-detector maximum-likelihood-ratio (MLR) statistic for different networks. Owing to the single synthetic data stream, the hybrid statistic gives low false alarms compared to the generic multi-detector MLR statistic and small fractional loss in the optimum SNR for a large range of binary inclinations. Thus, the hybrid statistic detect ∼ 7% more binary events compared to the generic multi-detector MLR statistic for a fixed false alarm probability of 10^−5 in the LIGO-Virgo network. |
