  In this brief note, we investigate some possible experimental consequences of
the de-Sitter or Anti-de-Sitter background spacetime structure for
d-dimensional evaporating black holes. Possible observational signatures in
Large Hadron Collider (LHC) events are considered in the framework of the
Arkani-Hamed-Dimopoulos-Dvali (ADD) braneworld model. Lower bounds on the value
of the bulk cosmological constant required to produce visible effects are
derived thanks to a dynamical Monte-Carlo simulation. This preliminary study
has to be refined by the accurate computation of the greybody factors. It opens
a new way to investigate the structure of non-asymptotically flat
higher-dimensional spacetimes.
