Hadronic tau jet reconstruction with particle flow algorithm at CMS

One of the most important decay modes of the charged Higgs boson is ${\rm H}^{\pm} \to \tau^{\pm}\nu_{\tau}$. The strategy used to reconstruct hadronically decaying taus using particle flow reconstruction algorithm at CMS is presented. The particle flow algorithm provides a complete reconstructed event description at the level of individually reconstructed particles, which improves the tau reconstruction performance compared to previous reconstruction methods.
