Useful Info for Black Holes and TeV Scale Gravity

Current Models

• Use semi-classical where cross section is geometric: σ ∝ πR² valid far above the Planck Scale M_D
• Closer to the planck scale Quantum Gravity effects are large and these are not fully understood, so place lower limit on BH mass above M_D
• Split fermion model explains range of SM Yukawa couplings via wave function overlaps across the split branes
• distance between quark & lepton branes constrained W cross section differences between qq'→W→qq' and qq'→W→lν
• In BlackMax the final burst phase takes care of the conservations like B, L, flavour, colour etc
• black holes lose all info on the initial state other than mass, spin, EM charge and colour

Questions

• What are mass multipoles?
