image superparticle and super-Yang–Mills theory in image harmonic superspace Original Research Article

We study the image harmonic superparticle model, both with and without central charge and quantize it. Since the central charge breaks the image R-symmetry group of the image superalgebra down to image, we consider the superparticle dynamics in image harmonic superspace with image harmonic variables. We show that the quantization of a massive superparticle with central charge leads to a superfield realization of the image massive vector multiplet in image harmonic superspace. In the massless case without central charge the superparticle quantization reproduces three different multiplets: the image SYM multiplet, the image gravitino multiplet and image supergravity multiplet. The SYM multiplet is described by six analytic superfield strengths with different types of analyticity. We show that these strengths solve the image SYM constraints and can be used for the construction of actions in image harmonic superspace.
