Is there some agreement about if the Wick rotation must produce exactly the same mass that the un-rotated equation, or is it more important to preserve some other quantity, say orbital momentum or whatever?(adsbygoogle = window.adsbygoogle || []).push({});

I am thinking on Hans' relativistic

[tex]

\beta^2 \over \sqrt {1-\beta^2}

[/tex]

because if we ask this quantity to be preserved up to sign, then the masses of W and Z are mapped to the (imaginary masses) of [candidate] Higgs boson and Top quark, which is pretty puzzling: 80.37 GeV becomes 122.38 i Gev and 91.187 GeV becomes 176.15 i GeV.
