SUMMARY:Searching for Sterile Neutrinos with KM3NeT/ORCA\, NPAC (Nucle
 ar/Particle/Astro/Cosmo) Forum\, Rogan Clark\, Université catholique 
 de Louvain\, Belgium
DESCRIPTION:Since the late 1990's\, a number of experiments have repor
 ted results that deviate from the standard model picture of neutrino o
 scillation\, suggesting the presence of a 4th neutrino state with larg
 e mass splitting of ~ 1eV2. These results have been contradicted by ot
 her experiments\, which place upper bounds on the existence of a poten
 tial fourth neutrino that conflict with the allowed phase space of the
  first group. KM3NeT/ORCA is a water cherenkov neutrino detector under
  construction in the Mediterranean Sea\, which is optimised to detect 
 oscillations of atmospheric neutrinos at O(10 GeV). This can be used t
 o search for oscillations into sterile neutrinos\, and thus provides a
 nother pathway to determining their existence\, or lack thereof. The l
 atest search for sterile neutrinos\, using the latest ORCA dataset com
 prising 1.4 Mton-yr of data\, will be reported and the future for ster
 ile neutrino searches discussed.
