A Magnetic Sweep Narrowed the Mirror-Neutron Gap
Laboratory measurements constrained ordinary-to-sterile neutron oscillations across a 0.3-to-22-peV mass-difference range.
Summary
Laboratory measurements constrained ordinary-to-sterile neutron oscillations across a 0.3-to-22-peV mass-difference range.
Fields from 5 to 360 microtesla set oscillation-time limits reaching about 20 seconds. In parts of the tested range, the laboratory constraint is stronger than a model-dependent neutron-star-cooling estimate; it is an exclusion result, not evidence that mirror neutrons exist.
Why it matters
Laboratory measurements constrained ordinary-to-sterile neutron oscillations across a 0.3-to-22-peV mass-difference range.
Limits and context
- In parts of the tested range, the laboratory constraint is stronger than a model-dependent neutron-star-cooling estimate; it is an exclusion result, not evidence that mirror neutrons exist.
