Abstract: We study some field representations of vector supersymmetry with superspin Y = 0 and Y = 1/2
and nonvanishing central charges. For Y = 0, we present two multiplets composed of four spinor
fields, two even and two odd, and we provide a free action for them. The main differences between
these two multiplets are the way the central charge operators act and the compatibility with the
Majorana reality condition on the spinors. One of the two is related to a previously studied spinning
particle model. For Y = 1/2, we present a multiplet composed of one even scalar, one odd vector
and one even selfdual two-form, which is a truncation of a known representation of the tensor
supersymmetry algebra in Euclidean spacetime. We discuss its rotation to Minkowski spacetime
and provide a set of dynamical equations for it, which are however not derived from a Lagrangian.
We develop a superspace formalism for vector supersymmetry with central charges and we derive
our multiplets by superspace techniques. Finally, we discuss some representations with vanishing
central charges.
