dc.description.abstract	This work focuses on the theoretical investigation of the coexistence of spin density wave(SDW) and superconductivity in superconducting BaFe2-xCoxAs2. By devel opi~g the model Hamiltonian for the system and using the double time temperature dependent Greens function formalism, we found mathematical expressions for su perconducting transition temperature (T (T c ) , spin density wave transition temperature sdw ), superconductivity order parameter (Lj.sc) and spin density wave order param eter (Lj.sdw), The phase diagrams of superconducting transition temperature versus superconductivity order parameter and spin density wave transition temperature ver sus spin density wave order parameter are obtained. By combining the two phase diagrams we have obtained a phase diagram which shows the possible coexistence of spin density wave and superconductivity in superconducting BaFe2-xCoxAs2. Key words: Spin Density Wave, critical temperature, critical magnetic field, order parameter and BaFe2-xCoxAs2.	en_US
