We consider the effect of relativistic boosts on single particle Gaussianwave packets. The coherence of the wave function as measured by the boostedobserver is studied as a function of the momentum and the boost parameter.Using various formulations of coherence it is shown that in general thecoherence decays with the increase of the momentum of the state, as well as theboost applied to it. Employing a basis-independent formulation, we showhowever, that coherence may be preserved even for large boosts applied onnarrow uncertainty wave packets. Our result is exemplified quantitatively forpractically realizable neutron wave functions.
