ON THE FISK-TAIT EQUATION FOR SPIN-3/2 FERMIONS INTERACTING WITH AN EXTERNAL MAGNETIC FIELD IN NONCOMMUTATIVE SPACE-TIME

In this paper, we investigated the Fisk-Tait equation in interaction with an external magnetic field in noncommutative space-time. The space-time noncommutativity is introduced through the Moyal-Weyl product method. Consequently, we studied the continuity equation in both commutative and noncommutative space-time; there we examined the influence of the space-time noncommutativity on the current density quadri-vector. Moreover, we find that the total charge obtained from the probability density is still indefinite even when space does not commute. Furthermore, we found the spin current density in the two different spin directions. We also investigated the linking between the fermions and the bosons in the Fock space using the Holstein-Primakoff transformation.
