In the context of gravity (general relativity and its variants, such as supergravity) what are called no-hair theorems are statements saying that or to which extent black hole spacetimes and more generally black brane spacetimes are characterized by their mass, angular momentum and charge, hence that they look much like macroscopic fundamental particles or fundamental branes (“black branes”).
The archetypical example is 4-dimensional Einstein-Maxwell theory, where the no-hair theorem asserts that all black hole solutions are entirely characterized by their mass, angular momentum and electric charge.

Generalizing to 4-dimensional Einstein-Yang-Mills theory with nonabelian gauge group, the situation becomes much more subtle. (…)
