- W2963264865 abstract "Using the worldline SU(2|1) superfield approach, we construct N = 4 superconformally invariant actions for the d = 1 multiplets (1, 4, 3) and (2, 4, 2). The SU(2|1) superfield framework automatically implies the trigonometric realization of the superconformal symmetry and the harmonic oscillator term in the corresponding component actions. We deal with the general N = 4 superconformal algebra D(2, 1; ) and its central-extended = 0 and = −1 psu(1, 1|2) ⊕su(2) descendants. We capitalize on the observation that D(2, 1; ) at 6= 0 can be treated as a closure of its two su(2|1) subalgebras, one of which defines the superisometry of the SU(2|1) superspace, while the other is related to the first one through the reflection of μ, the parameter of contraction to the flat N = 4, d = 1 superspace. This closure property and its = 0 analog suggest a simple criterion for the SU(2|1) invariant actions to be superconformal: they should be even functions of μ. We find that the superconformal actions of the multiplet (2, 4, 2) exist only at = −1, 0 and are reduced to a sum of the free sigma-model type action and the conformal superpotential yielding, respectively, the oscillator potential ∼ μ2 and the standard conformal inverse-square potential in the bosonic sector. The sigma-model action in this case can be constructed only on account of non-zero central charge in the superalgebra su(1, 1|2). PACS: 03.65.-" @default.
