Title: SEARCH FOR CHARGED HIGGS BOSONS WITH HADRONIC FINAL STATE IN CMS

The minimal extension to SM Higgs sector is to add a second complex doublet. This is required by many SUSY models, e.g. 2HDM and MSSM. Two doublets
lead to five physical scalar Higgs bosons: two of these are neutral and CP-even (light h_0 and heavier H_0), one is neutral and CP-odd (pseudoscalar
A), and two are charged (H+ and H-).

The search for charged Higgs bosons in CMS experiment at LHC is discussed. The main search channels for charged Higgs bosons in CMS are presented.
For H+ with mass smaller than m_top, the dominant production mode is gg-->t tbar --> bH+W-. For H+ with mass larger than m_top, associated
production gg --> tbH+ dominates. Both production modes can lead to a fully hadronic final state described by hadronically decaying tau, two
neutrinos and four hadronic jets (including two b-jets). This final state is interesting because it allows for the reconstruction of the transverse
mass of the charged Higgs boson.

Event selection and reconstruction methods and background measurement methods used for the fully hadronic final state are outlined. Recent
developments in these methods, such as invariant mass reconstruction and improved delta-phi cuts are presented. Preliminary results with full 2011
and 2012 data (integrated luminosities of 5.1 fb^(-1) and 20 fb^(-1), respectively) are presented.
