Chiral and flavor oscillations in the interaction picture

Le résumé fourni par la source

Abstract We provide a concise review of how chiral and flavor oscillations can be described in quantum field theory using a finite-time interaction picture approach, where the mass and mixing terms in the Lagrangian can be treated as perturbations. We derive the oscillation formulas for both chiral and flavor transitions and demonstrate that, within the adopted approximations, they match the exact results obtained through non-perturbative methods. Finally, we point out the strong similarities and the differences between these two phenomena.
