Tóm tắt
We quantize a rigid particle with a rigidity term proportional to the square of the extrinsic curvature of the particle's world-line using the Dirac-Bergmann scheme. Problems concerning higher order derivatives and second class constraints are avoided by using an action with an auxiliary field and one extra gauge symmetry. We find a spectrum with integer spin states only.
