Zitterwebegung and rest mass

[sweet springs]

Hello.
The speed of an elementary particle, for example an electron, in Zitterbewegung motion is c. So theory of relativity should say electron is massless particle ? Is Zitterbewegung not considered in theory in relativity ? Thanks.

Zitterbewegung is not a motion in any sense. Its just the artifact of misinterpreting a field(wave) equation as a single-particle Schrodinger-like equation!
