Quantum Mechanics of Neutrino Oscillations
Subtle problems in the theory of neutrino oscillations in vacuum are discussed [1]. It is shown that Lorentz invariance implies that in general flavor neutrinos in oscillation experiments are superpositions of massive neutrinos with different energies and different momenta. It is argued that a wave packet description of massive neutrinos is necessary in order to understand the physics of neutri...
متن کاملNeutrino Oscillations and Non-Hermitian Quantum Mechanics
In this dissertation we firstly present a brief review of the Standard Model of particle physics, focussing on aspects of the model that prove most relevant in the context of explaining the observed oscillation of neutrinos. The phenomenology of neutrino oscillations is then introduced, and different possible extensions to the Standard Model that would allow for non-zero neutrino masses, thereb...
متن کاملNeutrino Flavor States and the Quantum Theory of Neutrino Oscillations
The definition and derivation of flavor neutrino states in the framework of standard Quantum Field Theory is reviewed, clarifying some subtle points. It is shown that a flavor neutrino state that describes a neutrino produced or detected in a charged-current weak interaction process depends on the process under consideration and is appropriate for the description of neutrino oscillations as wel...
متن کاملQuantum Mechanics of Neutrino Oscillations - Hand Waving forPedestriansHarry
Why Hand Waving? All calculations in books describe oscillations in time. But real experiments don't measure time. Hand waving is used to convert the results of a \gedanken time experiment" to the result of a real experiment measuring oscillations in space. Right hand waving gives the right answer; wrong hand waving gives the wrong answer. Many papers use wrong handwaving to get wrong answers. ...
