Non‐Hermitian Lagrangian for Quasirelativistic Fermions

Advances in Mathematical Physics, 2014, vol. 2014, issue 1

Abstract: We present a Lorentz‐symmetry violating Lagrangian for free fermions, which is local but not Hermitian, whereas the corresponding Hamiltonian is Hermitian but not local. A specific feature of the model is that the dispersion relation is relativistic in both the IR and the UV but not in an intermediate regime, set by a given mass scale. The consistency of the model is shown by the study of properties expected in analogy with the Dirac Lagrangian.
