  Recent works have included the effect of rotation on simulations of black
hole events at the LHC, showing that the angular momentum of the black hole
cannot be ignored and it makes a non-trivial contribution for most of the
lifetime of the black hole. A key consequence of the rotation of the black hole
is that the Hawking radiation is no longer isotropic, making it more difficult
to infer space-time parameters from measurements of the emitted particles. In
this letter we study the angular distribution of the Hawking emission of
non-zero spin particles with specific helicity on the brane. We argue that the
shape of the distribution could be used as a measure of the angular momentum of
the black hole.
