Results of the six g-factor measurements carried out during CERN’s 2015/2016 accelerator shutdown between the 20 February 2016 and 5 March 2016. Based on this set of measurements we extract (/2)=2.7928465(23), as indicated by the red horizonal line. The green lines show the 95% confidence level error, the blue line represents the currently accepted value of the proton g-factor gp/2=2.792847350(9) (ref. 26). The error bars of the individual measurements are based on the uncertainties of the individual frequency measurements, which are dominated by the random walk in the magnetron mode.
