Generalised Schwarzschild metric from double copy of point-like charge solution in Born-Infeld theory
We discuss possible application of the classical double copy procedure to construction of a generalisation of the Schwarzschild metric starting from an α′-corrected open string analogue of the Coulomb solution. The latter is approximated by a point-like charge solution of the Born-Infeld action, whi...
