DESCRIPTION:The MiniBooNE experiment reported results from the analysis of
  $\\nu_e$ and $\\overline{\\nu}_e$ appearance searches\, which showed an e
 xcess of signal-like events at low reconstructed neutrino energies with re
 spect to the expected background. A proposed explanation for this anomaly 
 is based on the existence of a heavy ($\\sim 50$~MeV) sterile neutrino. Th
 ese $\\nu_h$ would be produced by $\\nu_\\mu$ electromagnetic interactions
 \, through a transition magnetic dipole moment\, and by neutral current in
 teractions on nuclei. A fraction of them decays radiatively inside the det
 ector. The emitted photons are misidentified as electrons or positrons in 
 MiniBooNE. \n\nWe have investigated the $\\nu_h$ production by coherent an
 d incoherent electroweak interactions on CH$_2$ and Ar targets\, present i
 n the MiniBooNE and the Short Baseline Neutrino (SBN) detectors (MicroBooN
 E\, SBND and ICARUS) at Fermilab. Following the $\\nu_h$ propagation insid
 e the detector we are able to obtain the energy and angular distributions 
 of the final photons. Within the valid range of model parameters\, we have
  obtained the best-fit parameters to describe the MiniBooNE excess of even
 ts. To further investigate this scenario\, we have obtained the expected t
 he signal at the SBN detectors. The distinctive shape and total number of 
 photon events from this mechanism  makes its experimental investigation fe
 asible.\n\nhttps://indico.ific.uv.es/event/3026/
