Query: Sterile Neutrino Production Through a Matter Effect Enhancement at Long
  Baselines   If sterile neutrinos have a neutral coupling to standard model fermions,
matter effect resonant transitions to sterile neutrinos and excess
neutral-current events could manifest at long baseline experiments. Assuming a
single sterile neutrino with a neutral coupling to fermionic matter, we
re-examine bounds on sterile neutrino production at long baselines from the
MINOS result $P_{\nu_{\mu} \rightarrow \nu_s} < 0.22$ (90% CL). We demonstrate
that sterile neutrinos with a neutral vector coupling to fermionic matter could
evade the MINOS limit, allowing a higher fraction of active to sterile neutrino
conversion at long baselines. Scanning the parameter space of sterile neutrino
matter effect fits of the LSND and MiniBooNe data, we show that in the case of
a vector singlet coupling of sterile neutrinos to matter, some favored
parametrizations of these fits would create neutral-current event excesses
above standard model predictions at long baseline experiments (e.g. MINOS and
OPERA).
