Abstract:We study subsolutions of the Dirac and Duffin-Kemmer-Petiau equations described in our earlier papers. It is shown that subsolutions of the Duffin-Kemmer-Petiau equations and those of the Dirac equation obey the same Dirac equation with some built-in projection operator. This covariant equation can be referred to as supersymmetric since it has bosonic as well as fermionic degrees of freedom.
“…Equations analogous to (15,16) appear also in the Duffin-Kemmer-Petiau theory of massive bosons [9]. Let us note finally that as shown in [24] the square of the Dirac operator is indeed supersymmetric, and this can be used for a convenient description of fluctuations around a self-dual monopole.…”

“…The operator P 4 can be written as P 4 = 1 4 (3+γ 5 − γ 0 γ 3 + iγ 1 γ 2 ) where γ 5 = iγ 0 γ 1 γ 2 γ 3 (similar formulae can be given for other projection operators P 1 , P 2 , P 3 , see [13] where another convention for γ µ matrices was however used). It thus follows that Equation (37) is given representation independent form and is Lorentz covariant (in [9] subsolutions of form Equation (37) were obtained for the free Dirac equation).…”

“…Our results derived lately fit into this broader picture. We have demonstrated that certain subsolutions of the free Duffin-Kemmer-Petiau (DKP) and the Dirac equations obey the same Dirac equation with some built-in projection operators [9]. We shall refer to this equation as supersymmetric since it has bosonic (spin 0 and 1) as well as fermionic spin 1 2 degrees of freedom.…”
Abstract:In the present paper we study subsolutions of the Dirac and Duffin-Kemmer-Petiau equations in the interacting case. It is shown that the Dirac equation in longitudinal external fields can be split into two covariant subequations (Dirac equations with built-in projection operators). Moreover, it is demonstrated that the Duffin-Kemmer-Petiau equations in crossed fields can be split into two 3 × 3 subequations. We show that all the subequations can be obtained via minimal coupling from the same 3 × 3 subequations which are thus a supersymmetric link between fermionic and bosonic degrees of freedom.

“…Our approach is A. Okniński ( ) PolitechnikaŚwiȩtokrzyska, Al. 1000-lecia PP 7, 25-314 Kielce, Poland e-mail: fizao@tu.kielce.pl based on the 3 × 3 equations, reviewed in the next Section, which are subequations of both the Dirac and DKP equations [18] (see also [19] for the interacting case) and thus provide a link between these equations. We interpret the 3 × 3 equations in Section 3, showing that they can be transformed nonlocally into the form which can be obtained from the Dirac equation by application of the unitary Melosh transformation.…”
We study a fermion-boson transformation. Our approach is based on the 3 × 3 equations which are subequations of both the Dirac and Duffin-Kemmer-Petiau equations and thus provide a link between these equations. We show that solutions of the free Dirac equation can be converted to solutions of spin-0 Duffin-Kemmer-Petiau equation and vice versa. Mechanism of this transition assumes existence of a constant spinor.
In this work we study supersymmetric model of ρ-meson propagation in quarkgluon plasma. Then we apply this method to total absorption cross sections of photon and photino. We use supersymmetric condition to find that absorption cross sections of photon should be equal to absorption cross sections of photino.
