Abstract
In most cosmological models, primordial black holes (pbh) should have
formed in the early Universe. Their Hawking evaporation into particles could
eventually lead to the formation of antideuterium nuclei.
This paper is devoted to a first computation of this antideuteron flux.
The production of these antinuclei is studied with a simple
coalescence scheme, and their propagation in the Galaxy is treated with
a well-constrained diffusion model.
We compare the resulting primary flux to the secondary background, due
to the spallation of protons on the interstellar matter.
Antideuterons are shown to be a very sensitive probe for
primordial black
holes in our Galaxy. The next generation of experiments should
allow investigators to significantly improve the current upper limit, nor even
provide the first
evidence of the existence of evaporating black holes.
