Role of Zero Modes in Quantization of QCD in Light-Cone Coordinates
Hiroyuki Fujita, Sh. M. Shvartsman
Two-dimensional heavy-quark QCD is studied in the light-cone coordinates with (anti-) periodic field boundary conditions. We carry out the light-cone quantization of this gauge inv…
Superparticle actions from superfields
R. Marnelius, Sh. M. Shvartsman
Gauge invariant complex covariant actions for superparticles are derived from the field equations for the chiral superfields in a precise manner. The massive and massless cases in…
Spinor and Isospinor Structure of Relativistic Particle Propagators
D. M. Gitman, Sh. M. Shvartsman
Representations by means of path integrals are used to find spinor and isospinor structure of relativistic particle propagators in external fields. For Dirac propagator in an exter…
Path Integrals over Velocities in Quantum Mechanics
D. M. Gitman, Sh. M. Shvartsman
Representations of propagators by means of path integrals over velocities are discussed both in nonrelativistic and relativistic quantum mechanics. It is shown that all the propaga…
