The new superalgebra describes the supersymmetries of generalized N = 1 , D = 4 superspace in the presence of a constant Abelian supersymmetric field strength background. Applying the techniques of nonlinear coset realization to the Maxwell supergroup we propose a new κ -invariant massless superparticle model providing a dynamical realization of the Maxwell superalgebra.4 p.application/pdfeng(c) American Physical Society, 2010Física de partículesÀlgebraParticle physicsAlgebrainfo:eu-repo/semantics/article5927912019-07-22info:eu-repo/semantics/openAccess
