Increase of the pion-kaon Hawking radiation from Schwarzschild black   holes by Dirac monopoles
  An algorithm for numerical computation of the barrier transparency for the potentials surrounding Schwarzschild black holes is described for massive scalar particles. It is then applied to calculate the total (including all particle species and the contributions of twisted field configurations connected with Dirac monopoles) luminosity for the pion-kaon Hawking radiation from a Schwarzschild black hole with mass $M=10^{12}$ g. It is found that the contribution due to monopoles can be of order 11% of the total pion-kaon luminosity.
