It was known that the no-hair theorem of black hole (BH) can be generalized to a system with a self-interacting complex scalar field with U(1) gauge interaction: there exists no spherically symmetric static solution of scalar field around a charged BH in an asymptotically flat spacetime. In this talk, I will explain that the proof of the theorem is not complete and there actually exists a static scalar hair for a charged BH. The scalar hair for the BH is spherically symmetric, which was missed for more than two decades despite its simplicity. I will also explain its stability against small perturbations as well as quantum tunneling process.
