Idea

By dilatino one refers to a superpartner of the dilaton.

Ambiguity of the nomenclature

In supergravity literature there is an ambiguity in the nomenclature relatively to the dilatino field.

  • Part of the literature uses the name “dilatino” to mean the superpartner λ αD αϕ\lambda_\alpha \coloneqq D_\alpha\phi of the scalar dilaton field ϕ\phi, which comes from the circular Kaluza-Klein compactification of the bosonic supervielbein given by e n=ϕ(dx n+A)e^n = \phi(\mathrm{d}x^n+A) in a nn-dimensional spacetime.

  • Part of the literature uses it to mean, instead, the spinor which comes from the circular Kaluza-Klein compactification of the fermionic supervielbein (i.e. of the gravitino) given by ψ nd α=ψ (n1)d α+χ αe n\psi^\alpha_{n\text{d}} = \psi^\alpha_{(n-1)\text{d}} + \chi^\alpha e^n in a nn-dimensional spacetime. See for instance (DFGT08).
