Abstract

We show that the X17 vector boson, introduced to explain the ⁸ Be anomalous decay, could play a crucial role in the explanation of the muon's (electron's) anomalous magnetic moment and the muonic Lamb shift. We further constrain the possible kinetic mixing with the U(1)_Y boson of the Standard Model by using the latest available data on the W boson mass.
