Understand

Recently, an extension of the standard model based on ideas of Lee and Wick has been discussed.

This theory is free of quadratic divergences and hence has a Higgs mass that is stable against radiative corrections.
Here, we address the question of whether or not it is possible to couple very heavy particles, with masses much greater than the weak scale, to the Lee-Wick standard model degrees of freedom and still preserve the stability of the weak scale.
We show that in the LW-standard model the familiar see-saw mechanism for generating neutrino masses preserves the solution to the hierarchy puzzle provided by the higher derivative terms.
