“…We ignore the influence of massive neutrinos throughout this study. The effect of massive neutrinos on the growth of structure is significantly scale dependent, but on present linear scales well below the horizon, k $ 0:01-0:1h Mpc À1 , the growth suppression from a normal neutrino mass hierarchy with P m $ 0:05 eV [21] is & 1% in GðzÞ and fðzÞGðzÞ and smaller for other observables. The maximum decrement in growth from nearly degenerate neutrinos with P m $ 0:5 eV (e.g.…”

Given a class of dark energy models, constraints from one set of cosmic acceleration observables make predictions for other observables. Here we present the allowed ranges for the expansion rate HðzÞ, distances DðzÞ, and the linear growth function GðzÞ (as well as other, derived growth observables) from the current combination of cosmological measurements of supernovae, the cosmic microwave background, baryon acoustic oscillations, and the Hubble constant. With a cosmological constant as the dark energy and assuming near-minimal neutrino masses, the growth function is already predicted to better than 2% precision at any redshift, with or without spatial curvature. Direct measurements of growth that match this precision offer the opportunity to stringently test and potentially rule out a cosmological constant. While predictions in the broader class of quintessence models are weaker, it is remarkable that they are typically only a factor of 2-3 less precise than forecasted predictions for future space-based supernovae and Planck CMB measurements. In particular, measurements of growth at any redshift, or the Hubble constant H 0 , that exceed ÃCDM predictions by substantially more than 2% would rule out not only a cosmological constant but also the whole quintessence class, with or without curvature and early dark energy. Barring additional systematic errors hiding in the data, such a discovery would require more exotic explanations of cosmic acceleration such as phantom dark energy, dark energy clustering, or modifications of gravity.

“…There is now experimentally strong proof of neutrino oscillations [21], which implies that they have mass, and hence there must exist a right handed component. Neutrinos were chosen to have no right component in the SM just because, at the time it was proposed, neutrinos were believed to have no mass at aIl.…”

“…In a number of experiments on solar, atmospheric, reactor and accelerator neutrinos, the mass differences between the three neutrino mass eigenstates and the three mixing angles have been measured. However, these experiments are not sensitive to the absolute scale of the neutrino mass which needs to be determined in an independent experiment [1][2][3][4][5].…”

Neutrino mass sensitivity by MAC-E-Filter based time-of-flight spectroscopy with the example of KATRIN

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims at a measurement of the neutrino mass with a 90% confidence limit (CL) sensitivity of 0.2 eV/c 2 by measuring the endpoint region of the tritium β decay spectrum from a windowless gaseous molecular tritium source using an integrating spectrometer of the magnetic adiabatic collimation with an electrostatic filter (MAC-E-Filter) type. We discuss the idea of using the MAC-E-Filter in a timeof-flight mode (MAC-E-TOF) in which the neutrino mass is determined by a measurement of the electron TOF spectrum that depends on the neutrino mass. MAC-E-TOF spectroscopy here is a very sensitive method since the β-electrons are slowed down to distinguishable velocities by the MAC-E-Filter. Their velocity depends strongly on their surplus energy above the electric retarding potential. Using MAC-E-TOF, a statistical sensitivity gain is expected. Because a small number of retarding-potential settings is sufficient for a complete 3
