要旨：The discovery of B_c meson, which consists of a Charm quark and a Beauty (Bottom) quark, complets the meson "periodic" table.This system of states is expected to have properties intermediate between chrmonium and botonium systems It is thus natural to investigate the properties of such states when produced in ordinary as well as some different environments, like high temperature, high density, or a deconfinemed one.
As a first step we have calculated the spectrum and lifetime of this meson with a relativistic approach in Betthe-Salpetert model using two reductions. We shall present our results in comparison with other calculations and experimental data.
