Straight-line string in the einbein field formalism
arXiv:hep-ph/9708319
Abstract
The canonical description of the straight-line string is given in the einbein field formalism. The system is quantized and Regge spectrum is reproduced. The covariant analogue of the Newton-Wigner coordinate is found, and peculiarities of the gauge fixing in τ-reparametrization group are discussed.
