Gamma-ray burst polarization reduction induced by the Lorentz invariance violation
Hai-Nan Lin, Xin Li, Zhe Chang
It has been observed that photons in the prompt emission of some gamma-ray bursts (GRBs) are highly polarized. The high polarization is used by some authors to give a strict constr…
Constraints on spacetime anisotropy and Lorentz violation from the GRAAL experiment
Zhe Chang, Sai Wang
The GRAAL experiment could constrain the variations of the speed of light. The anisotropy of the speed of light may imply that the spacetime is anisotropic. Finsler geometry is a r…
Lorentz and CPT violations in Finsler spacetime
Zhe Chang, Sai Wang
Standard model with intrinsic Lorentz and CPT violations is proposed in a Finsler geometric framework. We present explicitly Lorentz and CPT--breaking Lagrangians of the matter fie…
Lorentz invariance violation and electromagnetic field in an intrinsically anisotropic spacetime
Zhe Chang, Sai Wang
Recently, Kostelecky [V.A. Kostelecky, Phys. Lett. B 701, 137 (2011)] proposed that the spontaneous Lorentz invariance violation (sLIV) is related to Finsler geometry. Finsler spac…
Neutrino superluminality without Cherenkov-like processes in Finslerian special relativity
Zhe Chang, Xin Li, Sai Wang
Recently, Cohen and Glashow [A.G. Cohen, S.L. Glashow, Phys. Rev. Lett. {\bf 107}, 181803 (2011)] pointed out that the superluminal neutrinos reported by the OPERA would lose their…
OPERA superluminal neutrinos and Kinematics in Finsler spacetime
Zhe Chang, Xin Li, Sai Wang
The OPERA collaboration recently reported that muon neutrinos could be superluminal. More recently, Cohen and Glashow pointed that such superluminal neutrinos would be suppressed s…
