N= 2 Superconformal Gravitino in harmonic Superspace : Abstract / E.Ivanov, N.Zaigraev. – Text : electronic // Physics Letters B. – 2025. – Vol. 862. – P. 139333. – URL: https://doi.org/10.1016/j.physletb.2025.139333. – Bibliogr.: 34.

We present the harmonic superspace formulation of N = 2 gravitino multiplet, the simplest N = 2 half-integer spin gauge supermultiplet. It is shown that, quite similar to other N = 2 gauge multiplets, the gravitino supermultiplet is described by unconstrained analytic prepotentials h&sup(++*a) and h&sup(+++) which contain a conformal gravitino in the Wess-Zumino gauge. The analytic prepotentials naturally come out from the study of N = 2 supercurrents associated with hidden symmetries of N = 2 vector-hypermultiplet system. We construct the covariant  = 2 superfield strengths and the invariant N = 2 superfield actions and sketch their component contents. We observe that, at cost of introducing new auxiliary coordinates *Q&sup(*a)and *w&sup(+), the gravitino analytic prepotentials acquire a nice geometric interpretation as extra vielbeins of the covariant harmonic derivative D&sup(++). We speculate on a possible origin of the additional coordinates, including their relationship with N = 2 supertwistors.
