This exceptional result is attributed to a new vector gauge boson X（16.7）. We study the significance of this new boson, especially its effect in anomalies observed in long-lasting experimental measurements.By comparing the discrepancies between the Standard Model predictions and the experimental results, we find the values and regions of the couplings of X（16.7） to the muon and muon neutrino. In this work, we find that the newly observed boson X（16.7） may be the solution of both the Nu Te V anomaly and the（g-2）μ puzzle.展开更多
