摘要

The average of the six charged kaon mass measurements which we use in the Particle Listings is mK± =493.677 ± 0.013 MeV (S =2.4),(1) where the error has been increased by the scale factor S.The large scale factor indicates a serious disagreement between different input data.The average before scaling the error is mK± =493.677 ± 0.005 MeV, x2 =22.9 for 5 D.F.,Prob.=0.04％,(2) where the high x2 and correspondingly low x2 probability further quantify the disagreement.
