Lorentz and CPT breaking in gamma-ray burst neutrinos from string theory
A bstract Previous studies on high-energy gamma-ray burst neutrinos from IceCube suggest a neutrino speed variation at the Lorentz violation (LV) scale of ~6 . 4 × 10 17 GeV, with opposite velocity variances between neutrinos and antineutrinos. Within a spacetime foam model, inspired by string theory, we develop an …
