We study the St¨ uckelberg equation for a relativistic particle with two spin states S= 1 and
S= 0 in the presence of an external uniform magnetic field. The particle is described by an …

Fradkin's model for a spin-3/2 particle in the presence of external fields is investigated.
Applying the general Gel'fand–Yaglom formalism, we develop this model on the base of a …

The wave equation for the vector bispinor Ψ a (x), which describes a zero mass spin 3/2
particle in the Rarita–schwinger form, is transformed into a new basis of Ψ a (x), in which the …

We consider a confluent modification of the general Heun equation having three regular
singular points and an irregular singularity of rank one at infinity. We show that this equation …

We examine the basic matrix equation for a spin-2 field in spherical coordinates and a tetrad
of Minkowski spacetime. The technique of Wigner D-functions is used to separate the …

Recently, models for a spin 1/2 particle with two (or three) mass parameters were
developed. Specific features of these models are as follows. For corresponding two (or …

We study the problem of vector particles with electric quadrupole moment in presence of an
external Coulomb eld. Startingwith the relativistic Du n-Kemmer theory, we search for …

The relativistic wave equation is well-known for a spin 3/2 particle proposed by WE Pauli
and ME Fierz and based on the 16-component wave function with the transformation …
