Vogel universality and beyond
A. P. Isaev
For simple Lie algebras we construct characteristic identities for split (polarized) Casimir operators in representations and , where -- definin…
On BRST Lagrangian formulation of massless higher spin fields
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
The paper is dedicated to the blessed memory of Professor Vladislav Gavrilovich Bagrov, an outstanding Russian scientist in the area of theoretical and mathematical physics. He had…
On the realization of infinite (continuous) spin field representations in AdS space
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We study the symmetry properties of infinite spin fields in space which are involved in the Lagrangian model proposed in arXiv:2403.14446 where the main role is played…
BRST construction for infinite spin field on
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We generalize the first class constraints that describe the infinite spin irreducible Poincaré group representation in flat space to new first class constraints in spa…
Infinite (continuous) spin particle in constant curvature space
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We present a new particle model that generalize for constant curvature space an infinite spin particle in flat space. The model is described by commuting Weyl spinor additional coo…
Neutrino Mass in Effective Field Theory
A. V. Borisov, A. P. Isaev
In this review, the seesaw mechanism for generating the mass of active light neutrinos (both Majorana and Dirac) is considered on the basis of effective field theory. In particular…
Generalization of the Bargmann-Wigner approach to constructing relativistic fields
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We review the method for constructing local relativistic fields corresponding to the Bargmann-Wigner wave functions that describe the unitary irreducible representations of the $4D…
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…
Two-spinor description of massive particles and relativistic spin projection operators
A. P. Isaev, M. A. Podoinitsyn
On the basis of the Wigner unitary representations of the covering group ISL(2,C) of the Poincaré group, we obtain spin-tensor wave functions of free massive particles with arbitra…
