Towards Lagrangian construction for infinite half-integer spin field
I. L. Buchbinder, S. Fedoruk, A. P. Isaev +1
We formulate the conditions for the generalized fields in the space with additional commuting Weyl spinor coordinates which define the infinite half-integer spin representation of…
Massless infinite spin (super)particles and fields
I. L. Buchbinder, S. Fedoruk, A. P. Isaev
A new twistorial field formulation of a massless infinite spin particle is derived. We find a twistorial infinite spin field and derive its helicity decomposition. The twistorial e…
Twistorial and space-time descriptions of massless infinite spin (super)particles and fields
I. L. Buchbinder, S. Fedoruk, A. P. Isaev
We develop a new twistorial field formulation of a massless infinite spin particle. Unlike our previous approach arXiv:1805.09706, the quantization of such a world-line infinite sp…
Model of massless relativistic particle with continuous spin and its twistorial description
I. L. Buchbinder, S. Fedoruk, A. P. Isaev +1
We propose a new world-line Lagrangian model of the D=4 massless relativistic particle with continuous spin and develop its twistorial formulation. The description uses two Penrose…
Weinberg propagator of a free massive particle with an arbitrary spin from the BFV-BRST path integral
V. G. Zima, S. O. Fedoruk
The transition amplitude is obtained for a free massive particle of arbitrary spin by calculating the path integral in the index-spinor formulation within the BFV-BRST approach. No…
