Thursday after lunch: Neutrino
- Alexander Friedland
Six parameters enable us to compute all neutrino oscillations in the standard three-flavor neutrino mixing paradigm. Our measurements of these parameters have been steadily improving over time. With the unprecedented precision promised by the next-generation experiments, we re-evaluate our understanding of neutrino mixing by relaxing the three-flavor assumption, i.e., testing the unitarity of...
This talk will consider a new mechanism to produce anomalous tau neutrino appearance at the near detectors of beam-focused neutrino experiments, without extending the neutrino sector. The charged mesons (π±,K±) produced and focused in the target-horn system can decay to a neutrino-philic light mediator via the helicity-unsuppressed three-body decays. Such a mediator also can be produced via...
In the simple two-generation case the probability Pμτ is not affected by interactions of neutrinos in matter. But for three generation case at baselines of the order of 9000 km matter effects become important for this channel. This is a genuine three flavour effect. We study how the presence of non-standard interactions alters the Pμτ probability at these baselines. We observe large...
We present the first fully differential predictions for tau neutrino scattering in the energy region relevant to the DUNE experiment, including all spin correlations and all tau lepton decay channels. The calculation is performed using a generic interface between the neutrino event generator Achilles and the publicly available, general-purpose collider event simulation framework Sherpa.
In this talk, we investigate the excellent potential of future tau neutrino experiments in probing non-standard interactions and secret interactions of neutrino. Due to its ability identifying tau lepton, DUNE far detector could have superior sensitivity in probing the secret neutrino interactions by observing downward-going atmospheric neutrinos, compared to the short-baseline experiments in...
The detection of high-energy astrophysical neutrinos by IceCube has opened a new window on our Universe. While IceCube has measured the flux of these neutrinos at energies up to several PeV, much remains to be discovered regarding their origin and nature. Currently, measurements are limited by the small sample size of astrophysical neutrinos and by the difficulty of discriminating between...
