Title

Search for neutron-mirror neutron oscillations in low magnetic field with a beam experiment

Abstract

We propose to search for neutron-mirror neutron oscillations with a beam experiment, covering a wide range of magnetic field (from 50 to 1100 micro Tesla). In this range, only weak, indirect constraints exist and oscillations as short as (0.005-0.15) s are not excluded yet. We propose to probe oscillations with oscillation time up to 8 s at 3 sigma confidence level. For this experiment, we will reuse an existing ensemble of a 5-meter long solenoid and a mumetal shield. This ensemble is characterised.
