Searching for sterile neutrinos at the ESS$\nu$SB

Abstract

The ESS$\nu$SB project is a proposed neutrino oscillation experiment based on the European Spallation Source with the search for leptonic CP as its main aim. In this letter we show that a near detector at around 1 km distance from the beamline is not only very desirable for keeping the systematic errors affecting the CP search under control, but would also provide a significant sensitivity probe for sterile neutrino oscillations in the region of the parameter space favored by the long-standing LSND anomaly. We find that the effective mixing angle ${\theta }_{\mu e}$ can be probed down to ${\sin }^2(2{\theta }_{\mu e})\simeq 2(8)\cdot 10^{-3}$ at $5\sigma$ assuming 15% bin-to-bin (un)correlated systematics.
