Limits on neutrino Lorentz violation from multimessenger observations of TXS 0506+056
Physics Letters B, 2019 The observation by the IceCube Collaboration of a high-energy (E≳200 TeV) neutrino from the direction of the blazar TXS 0506+056 and the coincident observations of enhanced γ-ray emissions from the same object by MAGIC and other experiments can be used ...

On the lightlike Lorentz violation
Physics Letters B, 2020 We consider the lightlike spontaneous Lorentz invariance violation (SLIV) appearing through the zero “length-fixing” constraint put on a gauge vector field, AμAμ=0, and discuss its physical consequences in the framework of a conventional QED and beyond ...

Lorentz Symmetry Violation of Cosmic Photons
Universe, 2022 As a basic symmetry of space-time, Lorentz symmetry has played important roles in various fields of physics, and it is a glamorous question whether Lorentz symmetry breaks.

Radiative corrections and Lorentz violation
European Physical Journal C: Particles and Fields, 2020 Radiative corrections in Lorentz violating (LV) models have already received a lot of attention in the literature in recent years, with many instances where a LV operator in one sector of the Standard Model Extension (SME) generates, via loop corrections,

Journal of High Energy Physics, 2022 This work is an extension of our previous work [1] where we exploited holography to compute the complexity characteristics of Little String Theory (LST), a nonlocal, nongravitational field theory which flows to a local 2d CFT in the IR under RG via an ...

Contributions to Pion Decay from Lorentz Violation in the Weak Sector [PDF]
, 2013 Lorentz violation in the weak sector would affect the beta-decay lifetimes of pions. The decay amplitude may be rendered anisotropic, but only an isotropic violation of boost invariance can affect the net lifetime in the center of mass frame.

Lorentz violating Julia-Toulouse mechanism [PDF]
Physical Review D, 2007 We propose a new Lorentz invariant violating extension for the pure photonic sector of the Standard Model due to the condensation of topological defects in the context of the Julia-Toulouse mechanism. Possible physical consequences leading to direct measurable effects over the confining properties of the elementary particles are explored.

Lorentz violation and deep inelastic scattering
Physics Letters B, 2017 The effects of quark-sector Lorentz violation on deep inelastic electron–proton scattering are studied. We show that existing data can be used to establish first constraints on numerous coefficients for Lorentz violation in the quark sector at an ...

Quark-sector Lorentz violation in Z-boson production
Journal of High Energy Physics, 2021 Quark-sector Lorentz violation is studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange. We show the chiral nature of the weak interactions enables parity-violating and spin-dependent effects to be studied using ...

Searches for Violation of CPT Symmetry and Lorentz Invariance with Astrophysical Neutrinos
Universe, 2022 Neutrinos are a powerful tool for searching physics beyond the standard model of elementary particles. In this review, we present the status of the research on charge-parity-time (CPT) symmetry and Lorentz invariance violations using neutrinos emitted ...
