Abstract
Although the whole conformal group SO(4, 2) can be considered as a symmetry
in a classical massless field theory, the subgroup of special conformal transformations
(SCT), usually related to transitions to uniformly accelerated frames, causes
vacuum radiation in the corresponding quantum field theory, in analogy to the
Fulling-Unruh effect. The spectrum of the outgoing particles can be calculated
exactly and proves to be a generalization of the Planckian one.
