Description
We investigate the impact of a light sterile neutrino (∼ eV) on the prospective data expected
from currently running long-baseline experiments T2K and NOνA. If the future short baseline
experiments confirm the existence of an eV scale sterile neutrino, then the 3+1 scheme will
modify the mass hierarchy and CP-violation searches of the 3 active neutrino scenario in
these two experiments (taken alone and in combination). We perform a detailed study of the
sensitivity of these two experiments in the presence of new active sterile mixing angles and
Dirac CP-violating phases. T2K and NOνA may give the first indications of new CP phases
involved in such a 3+1 scenario and enable the extraction of more information on this enlarged
active sterile mixing parameter sector.
