Heavy charged Higgs boson production at next generation $\gamma\gamma$   colliders
  We investigate the scope of all relevant production modes of charged Higgs bosons in the MSSM, with mass larger than the one of the top quark, at future Linear Colliders operating in $\gamma\gamma$ mode at the TeV energy scale. Final states with one or two $H^\pm$ bosons are considered, as produced by both tree- and loop-level interactions
