MSW effect in quantum field theory
نویسندگان
چکیده
We show in detail the general relationship between the Schrödinger equation approach to calculating the MSW effect and the quantum field-theoretical S-matrix approach. We show the precise form a generic neutrino propagator must have to allow a physically meaningful ‘‘oscillation probability’’ to be decoupled from neutrino production fluxes and detection cross sections, and explicitly list the conditions—not realized in cases of current experimental interest—in which the field theory approach would be useful. @S0556-2821~99!01619-7#

Exploring the implications of the laws and principles of quantum physics in the field of talent (quantum theory of talent)
The issue of talent-discovering is one of the most important issues in the field of education and research that has always been a concern for educational systems. Studying the issues of identifying and guiding talented students can illuminate a large part of the activities of the executors and practitioners in order to accomplish their mission effectively. On the other hand, quantum physics has...
متن کاملNew Types of Accessible Environmental Influence on Neutrino Oscillation
To describe possible effects of medium, besides the hamiltonian introduced by Mikheev, Smirnov and Wolfenstein (MSW), in principle, there may exist new terms in the evolution equation for the neutrino oscillation due to the environment. Considering a two-energy-level quantum system: ν1 − ν2, two-species neutrino system which is embedded in a matter environment, we solve the neutrino evolution e...
متن کاملThe effect of first order magnetic field in a GaAs/AlAs spherical quantum dot with hydrogenic impurity
In this research, the effect of the first order magnetic field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot has been calculated. The perturbation method has been used within the framework of effective mass approximation for these calculations. Overall, the analysis shows that a proper choice of quantum dot radius and magnetic field can signifi...

In this study the interaction of cis-PtCl2(NH3)2 complex and graphene were investigated with MPW1PW91method in gas and solvent phases. The solvent effect was examined by the self-consistent reaction fieldtheory (SCRF) based on Polarizable Continuum Model (PCM). The selected solvents were chloroform,chlorobenzene, bromoethane, dimethyldisulfide, and dichloroethane. The solvent ...
