Abstract We developed the previously proposed theoretical framework based on the quantum field theory of open systems applied to neutrinos. Within this framework we have considered the neutrino evolution and neutrino flavour oscillations taking into account for the decay of a heavier neutrino state to a lighter neutrino state and to a massless particle, namely photons, dark photons, axion-like particles and gravitons. We have shown that the neutrino evolution accounting for the decays will be governed by the Lindblad master equation, in which the decoherence parameters are proportional to the neutrino decay rate.Abstract We developed the previously proposed theoretical framework based on the quantum field theory of open systems applied to neutrinos.

Experimental Evidence for Physical Reality of Theta Wave by Change in Radionuclide Decay Rates

Paulo Maurício

By analysis performed on two independent experiments on radionuclide decay rates, we inferred the physical reality of de Broglie waves. The unexpected result of a variation of decay rates of 32Si and 226Ra with Earth-Sun inverse squared distance, clearly related with solar neutrino flux, is accounted here as a physical action of de Broglie empty waves. The highly illusive neutrino could not account for that rate change unless we consider them as a quantum particle in the causal and non-linear quantum physics framework. Other experiment here studied relating solar flares and changes in 54Mn decay rate reinforce the assumption that the solar neutrino flux is the reason for that variation, with neutrino as a quantum particle in de Broglie framework. In addiction, over and above of discuss further possibilities to confirm, or not, ours conclusions, we report some experimental setups which isBy analysis performed on two independent experiments on radionuclide decay rates, we inferred the physical reality of de Broglie waves.

A decoherence explanation of the gallium neutrino anomaly

Yasaman Farzan, Thomas Schwetz

Gallium radioactive source experiments have reported a neutrino-induced event rate about 20\% lower than expected with a high statistical significance. We present an explanation of this observation assuming quantum decoherence of the neutrinos in the gallium detectors at a scale of 2~m. This explanation is consistent with global data on neutrino oscillations, including solar neutrinos, if decoherence effects decrease quickly with energy, for instance with a power law $E_ν^{-r}$ with $r\simeq 12$ . Our proposal does not require the presence of sterile neutrinos but implies a modification of the standard quantum mechanical evolution equations for active neutrinos.Gallium radioactive source experiments have reported a neutrino-induced event rate about 20\% lower than expected with a high statistical significance.
