Query: Laboratory bounds on Lorentz symmetry violation in low energy neutrino
  physics   Quantitative bounds on Lorentz symmetry violation in the neutrino sector have
been obtained by analyzing existing laboratory data on neutron $\beta$ decay
and pion leptonic decays. In particular some parameters appearing in the
energy-momentum dispersion relations for $\nu_e$ and $\nu_\mu$ have been
constrained in two typical cases arising in many models accounting for Lorentz
violation.
