Measurement of G Using a Cryogenic Torsion Pendulum: Post-2008 Analysis Review

Abstract

A measurement of G by our University of California, Irvine (UCI) team was reported at the 2008 Conference on Precision Electromagnetic Measurements (CPEM) [1]. This work has not yet been published; work continues to review and refine analysis of data from that measurement. We present in this paper the analysis and results of the measurement as it stood at the time of the 2008 conference, and discuss the analysis review under way. Our G measurement was conducted “blind”, keeping the exact value of the source mass hidden until just before the conference presentation.
