We plan to study states containing qq pairs of charmed or beauty quarks in addition to other pairs of qq . Such states are being found in present Laboratories, in the BABAR, CLEO, BES, BELLE collaborations, and will be also searched in the European FAIR facility in a few years. They are called X,Y,Z states and they challenge the standard structure of mesons as simple qq states. We have studied such states from the point of view of QCD sum rules for my Thesis, but they can also be efficiently studied from the perspective of effective theories in which the group of Valencia has a long tradition of work. Complementing the work done in Sao Paulo with work using effective theories will be very useful since predictions that stand using both procedures will be very solid and can be taken more seriously when it comes to propose experiments to search for these states. On the other hand, the work with effective theories allows one to gain some insight on the structure of these states which is complementary to the one obtained using the QCD sum rules. (AU)
