Abstract: This final degree project aims at studying the stability of a heavy tetraquark in nature using QCD formalism and some known approximations.We have chosen bbcc configuration. The procedure has been: firstly we have calculated the colour factor involved in the interaction of each quark inside a tetraquark system; secondly, using the colour factor, we have obtained the potential between the different quarks to thirdly, be able to determine the energy of this system using the Rayleigh-Ritz variational approximation. We finally have compared the thetraquark ground state energy with the energy of two mesons bc and we have observed that the first is smaller. Therefore we have concluded that our tetraquark is stable.
