The impact of the X17 boson on particle physics anomalies: muon anomalous magnetic moment, Lamb shift, W mass and dark charges
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.
