1. Dilaton

   In particle physics, the hypothetical dilaton particle is a particle of a scalar field φ {\displaystyle \varphi } that appears in theories with extra dimensions when the volume of the compactified dimensions varies. It appears as a radion in Kaluza–Klein theory's compactifications of extra dimensions. In Brans–Dicke theory of gravity, Newton's constant is not presumed to be constant but instead 1/G is replaced by a scalar field φ {\displaystyle \varphi } and the associated particle is the dilaton.

1. Dilaton

   In particle physics, a dilaton is a hypothetical particle. It also appears in Kaluza-Klein theory's compactifications of extra dimensions when the volume of the compactified dimensions vary. It is a particle of a scalar field Φ; a scalar field that always comes with gravity. In standard general relativity, Newton's constant, or equivalently, the Planck mass is always constant. If we "promote" this constant to a dynamical field, what we would get is the dilaton. So, in Kaluza-Klein theories, after dimensional reduction, the effective Planck mass varies as some power of the volume of compactified space. This is why volume can turn out as a dilaton in the lower dimensional effective theory. Although string theory naturally incorporates Kaluza–Klein theory, perturbative string theories, such as type I string theory, type II string theory and heterotic string theory, already contain the dilaton in the maximal number of 10 dimensions. However, on the other hand, M-theory in 11 dimensions does not include the dilaton in its spectrum unless it is compactified. In fact, the dilaton in type IIA string theory is actually the radion of M-theory compactified over a circle, while the dilaton in E8 × E8 string theory is the radion for the Hořava–Witten model.
