Gravitational effects on quantum coherence in neutrino oscillation

نویسندگان

چکیده

In this paper, we investigate the quantum coherence for two flavor neutrinos propagating in a Schwarzschild metric. fact, issue is explored both qualitatively via calculating parameter ${K}_{3}$ Leggett-Garg inequality and also quantitatively by evaluating ${l}_{1}$-norm, $\mathcal{C}(\ensuremath{\rho})$. Using weak field approximations, show that gravitational effects decrease maximum value of some intervals energy such way there no violation, while it leaves amount coherence, $\mathcal{C}(\ensuremath{\rho})$, unchanged.

Gravitational effects on the neutrino oscillation

The propagation of neutrinos in a gravitational field is studied. A method of calculating a covariant quantum–mechanical phase in a curved space–time is presented. The result is used to calculate gravitational effects on the neutrino oscillation in the presence of a gravitational field. We restrict our discussion to the case of the Schwarzschild metric. Specifically, the cases of the radial pro...

Gravitational effects on the neutrino oscillation in vacuum

The neutrino oscillation phenomenon has been discussed in the case of neutrinos propagating in a flat space–time both in the plane wave approach for highly relativistic neutrinos [1] and in the wave packet formalism [2]. In this note we present a generalization of the plane wave approach to the case of curved space–time [3–5]. In order to generalize the plane–wave approach to the case of a curv...

On the Quantum Mechanics of Neutrino Oscillation

We try to understand and to develop some of the basic quantum mechanics of neutrino oscillation. First, we observe that measurements which identify the physical neutrino (mass eigenstate) involved in each event of an experiment destroy any oscillation pattern. We explain how these measurements do that. Then, we construct a wave packet treatment of neutrino oscillation. We find that it gives the...

Testing Quantum Mechanics in Neutrino Oscillation

A scenario of testing quantum mechanics in neutrino oscillation is presented. The quantum mechanics violation(QMV) that is motivated by arguments based on quantum gravity is investigated in neutrino system. It is found that the evolution equation of density matrix including QMV effect is analytically resolvable for neutrino propagate in vacuum or in matter under adiabatic approximation. The ana...

Effects of neutrino oscillation on supernova neutrino: inverted mass hierarchy

We study the effects of neutrino oscillation on supernova neutrino in the case of the inverted mass hierarchy (m3 ≪ m1 < m2) as well as the normal mass hierarchy (m1 < m2 ≪ m3). Numerical analysis using a realistic supernova and presupernova model allows us to discuss quantitatively a possibility to probe neutrino oscillation parameters. We show that information about the mass hierarchy can be ...
