Life cycle of Mini Black Holes1 Formationlower bound on BH mass from area theorem (Yoshino & Nambu ’02)2 Balding phase: end state is Myers-Perry black hole3 Spindown phase: loss of angular momentum and mass4 Schwarzschild phase: decay via Hawking radiation5 Planck phase: M ∼ M PlGoal: more precise understanding of black hole formation⇒ compute mass and spin of final black hole⇒ input to event generators (TRUENOIR, Catfish, BlackMax, Charybdis2)Toy model: black hole collisions in higher dimensionsH.
