A novel magnetic trap for solving the neutron lifetime puzzle

The neutron lifetime puzzle has been an evolving and complicated issue since high precision lifetime measurements began in the late 1980s. Probably the most notably anomaly among many others is the 1% discrepancy between two sets of high precision measurements via the so-called "beam" and "bottle" approaches. Also related is the puzzle about the CKM unitarity. One of the possible explanations for such puzzles is from the newly proposed mirror matter model via ordinary-mirror neutron (n-n') oscillations. Anomalous lifetime results from previous magnetic trap measurements are discussed. A novel magnetic trap under specific geometries, as proposed, would produce extremely anomalous lifetimes (lower by >100 s) as predicted by the n-n' oscillation model. Furthermore, this unique trap is able to quantitatively address all possible neutron loss mechanisms and it will be a powerful tool for revealing new physics if it exists.
