Straight-line string in the einbein field formalism
Yu. S. Kalashnikova, A. V. Nefediev
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 t…

Relativistic quantum mechanics in the einbein field formalism
Yu. S. Kalashnikova, A. V. Nefediev
The system of two relativistic particles with einbein fields is quantized as a constrained system.A method of the introduction of the Newton--Wigner collective coordinate is discus…
