Query: Accommodating three low-scale anomalies (g-2, Lamb shift, and Atomki) in
  the framed standard model   The framed standard model (FSM) predicts a $0^+$ boson with mass around 20
MeV in the "hidden sector", which mixes at tree level with the standard Higgs
$h_W$ and hence acquires small couplings to quarks and leptons which can be
calculated in the FSM apart from the mixing parameter $\rho_{Uh}$. The exchange
of this mixed state $U$ will contribute to $g - 2$ and to the Lamb shift. By
adjusting $\rho_{Uh}$ alone, it is found that the FSM can satisfy all present
experimental bounds on the $g - 2$ and Lamb shift anomalies for $\mu$ and $e$,
and for the latter for both hydrogen and deuterium.
  The FSM predicts also a $1^-$ boson in the "hidden sector" with a mass of 17
MeV, that is, right on top of the Atomki anomaly $X$. This mixes with the
photon at 1-loop level and couples thereby like a dark photon to quarks and
leptons. It is however a compound state and is thought likely to possess
additional compound couplings to hadrons. By adjusting the mixing parameter and
the $X$'s compound coupling to nucleons, the FSM can reproduce the production
rate of the $X$ in beryllium decay as well as satisfy all the bounds on $X$
listed so far in the literature.
  The above two results are consistent in that the $U$, being $0^+$, does not
contribute to the Atomki anomaly if parity and angular momentum are conserved,
while $X$, though contributing to $g - 2$ and Lamb shift, has smaller couplings
than $U$ and can, at first instance, be neglected there.
  Despite the tentative nature of the 3 anomalies in experiment and of the FSM
as theory, the accommodation of the former in the latter has strengthened the
credibility of both. If this FSM interpretation were correct, it would change
the whole aspect of the anomalies from just curiosities to windows into a vast
hitherto hidden sector comprising at least in part the dark matter which makes
up the bulk of our universe.
