- Tevatron - probing TeV-scale gravity today (2002)
- The production of black holes at Tevatron and LHC in spacetimes with compactified space-like large extra dimensions is studied. Either black holes can already be observed in ¯ pp collisions at s = 1.8 TeV or the fundamental gravity scale has to be above 1.4 TeV. At LHC the creation of a large number of quasi-stable black holes is predicted, with lifetimes beyond several hundred fm/c. A cut-off in the high-PT jet cross section is shown to be a unique signature of black hole production. This signal is compared to the jet plus missing energy signature due to graviton production in the final state as proposed by the ATLAS collaboration.
- Suppression of high-P T jets as a signal for large extra dimensions and new estimates of lifetimes for meta stable micro black holes : from the early universe to future colliders (2002)
- We address the production of black holes at LHC in space times with compactified space-like large extra dimensions (LXD). Final state black hole production leads to suppression of high-PT jets, i.e. a sharp cut-o in (pp!jet+X). This signal is compared to the jet plus missing energy signature due to graviton production in the final state as proposed by the ATLAS collaboration. Time evolution and lifetimes of the newly created black holes are calculated based on the micro- canonical formalism. It is demonstrated that previous lifetime estimates of micro black holes have been dramatically underestimated. The creation of a large number of quasi-stable black holes is predicted with life times of hundred fm/c at LHC. Medium modifications of the black holes evaporation rate due to the quark gluon plasma in relativistic heavy ion collisions as well as provided by the cosmic fluid in the early universe are studied
- Quasi-stable black holes at the large hadron collider (2002)
- We address the production of black holes at LHC and their time evolution in space times with compactified space like extra dimensions. It is shown that black holes with life times of several hundred fm/c can be produced at LHC. The possibility of quasi-stable remnants is discussed.
- Black hole production in large extra dimensions at the Tevatron : possibility for a first glimpse on TeV scale gravity (2002)
- The production of black holes in large extra dimensions is studied for Tevatron energies. We find that black holes may have already been created in small abundance in pp collisions at ps = 1.8 TeV. For the next Tevatron run (ps = 2.0 TeV) large production rates for black holes are predicted.
