Query: Abelian-Higgs hair on stationary axisymmetric black hole in
  Einstein-Maxwell-axion-dilaton gravity   We studied, both analytically and numerically, an Abelian Higgs vortex in the
spacetime of stationary axisymmetric black hole being the solution of the
low-energy limit of the heterotic string theory, acted as hair on the black
hole background. Taking into account the gravitational backreaction of the
vortex we show that its influence is far more subtle than causing only a
conical defect. As a consequence of its existence, we found that the ergosphere
was shifted as well as event horizon angular velocity was affected by its
presence. Numerical simulations reveal the strong dependence of the vortex
behaviour on the black hole charge and mass of the Higgs boson. For large
masses of the Higgs boson and large value of the charge, black hole is always
pierced by an Abelian Higgs vortex, while small values of the charge and Higgs
boson mass lead to the expulsion of Higgs field.
