摘要：
If there is Lorentz symmetry violation in the t quark sector of the standard model, changes to particles' dispersion relations might allow for the existence of stable top-flavored hadrons. Observations of the survival of high-energy gamma-rays over astrophysical distances can be used to place constraints on Lorentz violation coefficients in the t sector at similar to 10(-4)-10(-6) levels of precision.
