Query: Two-Higgs doublet solution to the LSND, MiniBooNE and muon $g-2$
  anomalies   We show that one of the simplest extensions of the Standard Model, the
addition of a second Higgs doublet, when combined with a dark sector singlet
scalar, allows us to: $i)$ explain the long-standing anomalies in the Liquid
Scintillator Neutrino Detector (LSND) and MiniBooNE (MB) while maintaining
compatibility with the null result from KARMEN, $ii)$ obtain, in the process, a
portal to the dark sector, and $iii)$ comfortably account for the observed
value of the muon $g-2$. Three singlet neutrinos allow for an understanding of
observed neutrino mass-squared differences via a Type I seesaw, with two of the
lighter states participating in the interaction in both LSND and MB. We obtain
very good fits to energy and angular distributions in both experiments. We
explain features of the solution presented here and discuss the constraints
that our model must satisfy. We also mention prospects for future tests of its
particle content.
