Superluminal Neutrinos in the Minimal Standard Model Extension

, 2012
Most recently, the measurement of the neutrino velocity with the OPERA detector in the CNGS beam shows unexpected indication, that the muon neutrino velocity, $v_{\nu}$, exceeds the velocity of light in the vacuum, $c$, which is obviously in ...

Commissioning of the vacuum system of the KATRIN Main Spectrometer [PDF]

, 2016
The KATRIN experiment will probe the neutrino mass by measuring the beta-electron energy spectrum near the endpoint of tritium beta-decay. An integral energy analysis will be performed by an electro-static spectrometer (Main Spectrometer), an ultra-high ...

Clock-transport synchronisation for neutrino time-of-flight measurements

, 2012
A method to synchronise, at the sub-nanosecond level, clocks used for neutrino time-of-flight measurements is proposed. Clocks situated near the neutrino source and target are compared with a moveable clock that is transported between them.

Dark energy properties from large future galaxy surveys

, 2013
We perform a detailed forecast on how well a {\sc Euclid}-like survey will be able to constrain dark energy and neutrino parameters from a combination of its cosmic shear power spectrum, galaxy power spectrum, and cluster mass function measurements.

Constraints on neutrino and dark radiation interactions using cosmological observations

, 2012
Observations of the cosmic microwave background (CMB) and large-scale structure (LSS) provide a unique opportunity to explore the fundamental properties of the constituents that compose the cosmic dark radiation background (CDRB), of which the three ...

Neutrinos in Non-linear Structure Formation - a Simple SPH Approach

, 2011
We present a novel method for implementing massive neutrinos in N-body simulations. Instead of sampling the neutrino velocity distribution by individual point particles we take neutrino free-streaming into account by treating it as an effective redshift ...

Weighing the Neutrino

, 2013
We investigate the potential of short-baseline experiments in order to measure the dispersion relation of the (muon) neutrino, with a prospect of eventually measuring the neutrino mass. As a byproduct, the experiment would help to constrain parameters of

Uncertainties in Constraints from Pair Production on Superluminal Neutrinos

, 2012
The use of the vacuum lepton pair production process ($\nu \to \nu e^- e^+ $), a viable reaction for superluminal neutrinos, to put constraints on Lorentz violations requires a dynamical framework.

Lorentz and CPT violation in the Neutrino Sector

, 2013
Searches for Lorentz and CPT violation using neutrino oscillations and the prospects for future tests using neutrino time-of-flight measurements and beta-decay experiments are presented.Comment: Presented at the Sixth Meeting on CPT and Lorentz Symmetry,
