We study the mesons matter D-\bar{D} in the framework of sigma and omega meson exchange model using Walecka's mean field theory. We choose the equal number of D and anti-D meson then we get =0 and the field sigma exhibits a critical temperature around 1.2 GeV. We investigate effective mass, pressure, energy density and energy per pair. We conclude that this matter is a gas and these results are not favorable for the existence of D-\bar{D} bound state.
