@article{Buchbinder2008N4SA, title={N=4 superparticle and super-Yang–Mills theory in USp(4) harmonic superspace}, author={Ioseph L. Buchbinder and Olaf Lechtenfeld and Igor B. Samsonov}, journal={Nuclear Physics}, year={2008}, volume={802}, pages={208-246} }

Abstract We study the N = 4 harmonic superparticle model, both with and without central charge and quantize it. Since the central charge breaks the U ( 4 ) R-symmetry group of the N = 4 superalgebra down to USp ( 4 ) , we consider the superparticle dynamics in N = 4 harmonic superspace with USp ( 4 ) / ( U ( 1 ) × U ( 1 ) ) harmonic variables. We show that the quantization of a massive superparticle with central charge leads to a superfield realization of the N = 4 massive vector multiplet in N…
