A bstract We consider quantum-decoherence effects in neutrino oscillation data. Working the open quantum system framework we adopt a phenomenological approach that allows to parameterize energy dependence of decoherence effects. several models. analyze data from reactor experiments RENO, Daya Bay and KamLAND accelerator NOvA, MINOS/MINOS+ T2K. obtain updated constraints on parameters quantifying strength damping effects, which can be as low Γ ij ≲ 8 × 10 − 27 GeV at 90% confidence level some...
Neutrinos undergoing stochastic perturbations as they propagate experience decoherence, damping neutrino oscillations over distance. Such may result from fluctuations in space-time itself if gravity is a quantum force, including interactions between neutrinos and virtual black holes. In this work we model the influence of heuristic neutrino-virtual hole interaction scenarios on propagation evaluate resulting signals astrophysical atmospheric neutrinos. We derive decoherence operators...
One of the most common expectations a quantum theory gravity is that spacetime uncertain or fluctuating at microscopic scales, making it stochastic medium for particle propagation. Particles traversing this may experience fluctuations in travel times velocities, together referred to as lightcone fluctuations, with even very small effects potentially accumulating into observable signals over large distances. In work we present heuristic model and study resulting modifications neutrino...
Abstract The Muon g -2 Experiment at Fermilab uses a gaseous straw tracking detector to make detailed measurements of the stored muon beam profile, which are essential for experiment achieve its uncertainty goals. Positrons from decays spiral inward and pass through before striking an electromagnetic calorimeter. is therefore located inside vacuum chamber in region where magnetic field large non-uniform. As such, must have low leak rate maintain high-quality vacuum, be non-magnetic so as not...
The 3$\nu$ paradigm can be tested with precision measurements of the unitarity Pontecorvo–Maki–Nakagawa–Sakata (PMNS) neutrino mixing matrix. However, such tests are hampered by low $\nu_{\tau}$ oscillation measurements, and new required. A recent world-leading measurement appearance DeepCore sub-array IceCube observatory is presented, as well future prospects from upcoming Upgrade.
This is the report from Snowmass NF01 topical group and colleagues on current status expected future progress to understand three-flavor neutrino oscillation picture.
In neutrino experiments sensitive to multiple flavors, the analyzers may be presented with a choice of treating uncertainties on respective cross sections in correlated or an uncorrelated manner. This study focuses charged current deep inelastic scattering (CC DIS) channel both muon and tau neutrinos. We evaluate ratio leading-order $\nu_{\tau}$ $\nu_{\mu}$ derive its uncertainty from underlying parton distribution functions (PDFs). find that, for energies above 5 GeV, PDF-driven section is...
