Neutrino quantum decoherence in a fluctuating ALPs field

Year: 2025

Type: article

Abstract: The evolution of neutrinos in a fluctuating classical axionlike particles (ALPs) field is investigated. The equation for the neutrino density matrix is obtained in the Redfield form, and the corresponding dissipative matrix is derived. Estimates on the ALP-neutrino coupling constants are obtained using the limits on the decoherence parameter determined from the analysis of reactor neutrino experiments data.
