Variation of ground state B_c and B*_c meson masses for various n values

One of the most challenging field in theoretical particle physics is heavy quark physics. The huge amount of data available on hadrons needs to be explained in order to explore this field. Experimentally if one finds the need of high energy particles that can probe quark level physics, theoretically a suitable model is required to explain the properties such as mass spectrum, decays, reaction mechanism and bound state behaviours of those mesons which involve these quarks. In this line B_c meson is of significance when compared to flavour symmetric cc¯ and bb¯ meson states because it is the only meson composed of a b-quark and c¯ quark and is the first particle containing both b and c quarks. The B_c is the lowest mass bound state of c and b quarks which is expected to be a pseudo scalar meson predicted by the Standard Model
