Lorentz and CPT violation: a simple neutrino-oscillation model
We present a three-parameter model for three flavors of massless left-handed neutrinos with Fermi-point splitting and tri-maximal mixing angles. One of these parameters is the T–violating phase δ, for which the experimental results from K2K and KamLAND appear to favor a nonzero value. Future experiments, in particular MINOS, will be able to test this simple model. Possible implications for neut...
متن کاملAstrophysical Tests of Lorentz and CPT Violation with Photons
A general framework for tests of Lorentz invariance with electromagnetic waves is presented, allowing for operators of arbitrary mass dimension. Signatures of Lorentz violations include vacuum birefringence, vacuum dispersion, and anisotropies. Sensitive searches for violations using sources such as active galaxies, gamma-ray bursts, and the cosmic microwave background are discussed. Direction-...
متن کاملNeutrino oscillations, Lorentz=CPT violation, and dark energy
If dark energy (DE) couples to neutrinos, then there may be apparent violations of Lorentz=CPT invariance in neutrino oscillations. The DE-induced Lorentz=CPT violation takes a specific form that introduces neutrino oscillations that are energy independent, differ for particles and antiparticles, and can lead to novel effects for neutrinos propagating through matter. We show that ultra-high-ene...
متن کاملTheory and Tests of Cpt and Lorentz Violation
Nature appears to be covariant both under the discrete transformation CPT, formed from the product of charge conjugation C, parity inversion P, and time reversal T, and under the continuous Lorentz transformations including rotations and boosts. The CPT theorem links these symmetries, stating that under mild technical assumptions CPT is an exact symmetry of local Lorentzcovariant field theories...
متن کاملCPT violation implies violation of Lorentz invariance.
A interacting theory that violates CPT invariance necessarily violates Lorentz invariance. On the other hand, CPT invariance is not sufficient for out-of-cone Lorentz invariance. Theories that violate CPT by having different particle and antiparticle masses must be nonlocal.
