11º Seminário GIFT/2020

Resumo: We study the tunneling probability of a massive (mw) uncharged scalar packet out from a near-extremal, static charged black hole (with mass M and charge Q≲M). We show that there is indeed a net probability that a massive uncharged particle tunnels out from the black hole so that the final state (with new mass M′≡ M−mw) does violate the cosmic censorship conjecture. Nevertheless, the typical time for such a black hole to discharge (i.e, to absorb charge −Q from its surroundings and then become neutral) is much smaller than the tunneling time; therefore, the violation is never attained in practice. Even for a completely isolated black hole (should it exist), the standard time dilation near the horizon stretches the typical violation time scale to unobservable values.
