| Abstract: | Superconformal multiplet calculus provides a systematic method to construct higher derivative invariants in Poincare supergravity. In this context, multiplets in conformal supergravity are of interest. The minimal multiplet containing the gauge fields of the superconformal algebra is called as the Weyl multiplet. In five dimensions, it was shown that there are two such Weyl multiplets that differ in their auxiliary field content. The new Weyl multiplet contains a real scalar field of Weyl weight +1 and was named as dilaton Weyl multiplet. This was obtained using two different routes. We will see that the two routes lead to two different (new) multiplets in four dimensions. One of these is the dilaton Weyl multiplet in four dimensions and the other, is the 24+24 real scalar multiplet. Further, we will see the reduction of this multiplet to an 8+8 restricted multiplet and a precise embedding of the known 8+8 tensor multiplet inside this multiplet. We will discuss the possible future directions. |
