Search for quantum decoherence in neutrino oscillations with six detection units of KM3NeT/ORCA

Abstract Neutrinos described as an open quantum system may interact with the environment which introduces stochastic perturbations to their quantum phase. This mechanism leads to a loss of coherence along the propagation of the neutrino - a phenomenon commonly referred to as decoherence - and ultimately, to a modification of the oscillation probabilities. Fluctuations in space-time, as envisaged by various theories of quantum gravity, are a potential candidate for a decoherence-inducing environment. Consequently, the search for decoherence provides a rare opportunity to investigate quantum gravitational effects which are usually beyond the reach of current experiments. In this work, quantum decoherence effects are searched for in neutrino data collected by the KM3NeT/ORCA detector from January 2020 to November 2021. The analysis focuses on atmospheric neutrinos within the energy range of a few GeV to 100 GeV. Adopting the open quantum system framework, decoherence is described in a phenomenological manner with the strength of the effect given by the parameters Γ 21 and Γ 31 . Following previous studies, a dependence of the type Γ ij ∝ ( E / E 0 ) n on the neutrino energy is assumed and the cases n = -2,-1 are explored. No significant deviation with respect to the standard oscillation hypothesis is observed. Therefore, 90% CL upper limits are estimated as Γ 21 < 4.6· 10 21 GeV and Γ 31 < 8.4· 10 21 GeV for n = -2 and Γ 21 < 1.9· 10 -22 GeV and Γ 31 < 2.7· 10 -22 GeV for n = -1, respectively.

Abstract

Abstract Neutrinos described as an open quantum system may interact with the environment which introduces stochastic perturbations to their quantum phase. This mechanism leads to a loss of coherence along the propagation of the neutrino - a phenomenon commonly referred to as decoherence - and ultimately, to a modification of the oscillation probabilities. Fluctuations in space-time, as envisaged by various theories of quantum gravity, are a potential candidate for a decoherence-inducing environment. Consequently, the search for decoherence provides a rare opportunity to investigate quantum gravitational effects which are usually beyond the reach of current experiments. In this work, quantum decoherence effects are searched for in neutrino data collected by the KM3NeT/ORCA detector from January 2020 to November 2021. The analysis focuses on atmospheric neutrinos within the energy range of a few GeV to 100 GeV. Adopting the open quantum system framework, decoherence is described in a phenomenological manner with the strength of the effect given by the parameters Γ 21 and Γ 31 . Following previous studies, a dependence of the type Γ ij ∝ ( E / E 0 ) n on the neutrino energy is assumed and the cases n = -2,-1 are explored. No significant deviation with respect to the standard oscillation hypothesis is observed. Therefore, 90% CL upper limits are estimated as Γ 21 < 4.6· 10 21 GeV and Γ 31 < 8.4· 10 21 GeV for n = -2 and Γ 21 < 1.9· 10 -22 GeV and Γ 31 < 2.7· 10 -22 GeV for n = -1, respectively.
