Test of Lorentz Violation with Astrophysical Neutrino Flavor at IceCube

  title={Test of Lorentz Violation with Astrophysical Neutrino Flavor at IceCube},
  author={Teppei Katori and Carlos A. Arguelles and Jordi Salvado},
  journal={CPT and Lorentz Symmetry},
The high-energy astrophysical neutrinos recently discovered by IceCube opened a new way to test Lorentz and CPT violation through the astrophysical neutrino mixing properties. The flavor ratio of astrophysical neutrinos is a very powerful tool to investigate tiny effects caused by Lorentz and CPT violation. There are 3 main findings; (1) current limits on Lorentz and CPT violation in neutrino sector are not tight and they allow for any flavor ratios, (2) however, the observable flavor ratio on…

Quest for new physics using astrophysical neutrino flavour in IceCube
We have detected astrophysical neutrinos in IceCube that can be used to probe astrophysical sources at ultra high scales. Here we report a search for anomalous space time effects using astrophysical
Astrophysical Neutrinos in Testing Lorentz Symmetry
An overview of searches related to neutrinos of astronomical and astrophysical origin performed within the framework of the Standard-Model Extension is provided. For this effective field theory, key
Lorentz Symmetry and High-Energy Neutrino Astronomy
The search of the violation of Lorentz symmetry, or Lorentz violation (LV), is an active research field. The effects of LV are expected to be very small, and special systems are often used to search
Phenomenological Effects of CPT and Lorentz Invariance Violation in Particle and Astroparticle Physics
The state of art for astroparticle physics, quantum field theory, quantum gravity, and neutrino beams are discussed, with some interesting new proposals, both from a theoretical and phenomenological point of view.
Formal Developments for Lorentz-Violating Dirac Fermions and Neutrinos
The main finding is that the neutrino dispersion equation has the same structure in terms of Lorentz-violating operators as that of a modified single-fermion Dirac theory.
Probing Lorentz Invariance Violation with atmospheric neutrinos at INO-ICAL
Abstract The possibility of Lorentz Invariance Violation (LIV) may appear in unified theories, such as string theory, which allow the existence of a new space-time structure at the Planck scale (Mp
Implications of SU(2)L gauge invariance for constraints on Lorentz violation
Abstract Lorentz invariance may only be broken far above the electroweak scale, since violations are experimentally stringently constrained. Therefore, the Standard-Model Extension parameterizing

IceCube high-energy starting event sample: Description and flux characterization with 7.5 years of data
The IceCube Neutrino Observatory has established the existence of a high-energy all-sky neutrino flux of astrophysical origin. This discovery was made using events interacting within a fiducial
New Physics in Astrophysical Neutrino Flavor (NuFact 2016)
Astrophysical neutrinos are powerful tools to study fundamental properties of particle physics. We perform a general new physics study on ultra high energy neutrino flavor content by introducing
