  We examine experimental signatures of TeV-mass black hole formation in heavy
ion collisions at the LHC. We find that the black hole production results in a
complete disappearance of all very high $p_T$ ({$> 500$} GeV) back-to-back
correlated di-jets of total mass {$M > M_f \sim 1$}TeV. We show that the
subsequent Hawking-decay produces multiple hard mono-jets and discuss their
detection. We study the possibility of cold black hole remnant (BHR) formation
of mass $\sim M_f$ and the experimental distinguishability of scenarios with
BHRs and those with complete black hole decay. Finally we point out that a
Heckler-Kapusta-Hawking plasma may form from the emitted mono-jets. In this
context we present new simulation data of Mach shocks and of the evolution of
initial conditions until the freeze-out.
