Description
Parity-conjugated copies in the weak interactions of Standard Model particles, so called mirror-particles, could provide answers for several standing issues in physics today. Mixing between neutrons and mirror-neutrons in particular would violate baryon number conservation, a necessary ingredient for baryogenesis.
The mirror-neutron experiment at PSI searches for neutron to mirror-neutron oscillations in the presence of a non-zero mirror magnetic field by looking for anomalous neutron losses of stored ultracold neutrons (UCN). Data-taking was completed in 2021 and the analysis is ongoing. We present the analysis principle, based on Monte Carlo simulations and precise magnetic field maps, and show preliminary results.
