Rigid particle revisited: extrinsic curvature yields the Dirac equation    [PDF]

Alexei Deriglazov, Armen Nersessian

We analyze in details the quantization procedure for relativistic particle with higher-derivative term linear on the first extrinsic curvature (rigidity). We find that, contrary to common opinion, its quantization in terms of $so(3.2)$-algebra yields massive Dirac equation.
