Description
I will summarise recent progress in the formulation of flavour mixing and oscillations in pseudo-Hermitian quantum theories with non-Hermitian mass mixing matrices [arXiv: 2302.11666]. Such non-Hermitian quantum theories are made viable by the existence of a discrete anti-linear symmetry of the Hamiltonian, which ensures that single-particle states have real energies. I will describe the self-consistent construction of oscillation and survival probabilities that are consistent with positivity and unitarity, and highlight features of these pseudo-Hermitian flavour oscillations that are unique compared to their Hermitian counterparts.
