Description
The "proton size puzzle'' and the "muon anomalous moment problem'' are incomplete descriptions of significant discrepancies between experiments and standard model calculations. Actually the field has confronted a new regime of ultra-precise physics where traditional piece-meal analysis methods are no longer self-consistent. Determining the proton size $r_{p}$, the Rydberg constant $R_{\infty}$, the fine structure constant $\alpha$ and electron mass $m_{e}/h$ is an inextricably coupled problem at current levels of precision. In being based on assumptions about the fundamental constants, the "muon-physics'' discrepancies have not actually been shown to come from the muon sector. We have conducted a new global fit to the entire body of precision experimental data and electroweak theory. Least-squares fits to all the fundamental constants are made with and without a generic ``no-name'' boson, of undetermined spin, that interacts universally with leptons and hadrons proportional to electric charge. The analysis discovers a new local minimum of best fit statistic, where all of $r_{p}, \, R_{\infty}, \, \alpha,\, m_{e}/h$ have new values compared to previous work. The study is the first to consistently accommodate all the high-precision data. A new particle, similar to the ``dark photon'' but differing in detail, is predicted to be observed in electron- and muon-based experiments.
