Query: The $h \to 4 \ell$ spectrum at low $m_{34}$: Standard Model vs. light
  New Physics   We analyze $h\to 4\ell$ decays in the kinematical region where the dilepton
pair of low invariant mass ($m_{34}$) is not far from QCD resonances ($\Psi$
and $\Upsilon$ states). On the one hand, we present precise predictions of the
spectrum within the Standard Model, taking into account non-perturbative QCD
effects. On the other hand, we illustrate the sensitivity of this spectrum to
New Physics models predicting the existence of new exotic light states. In
particular, we show that parameter regions of models relevant to explain the
$(g-2)_\mu$ anomaly could be probed in the future by means of $h\to 4\ell$
decays.
