### Description

We develop a very first model to describe the energy dependence of the tetraquark production cross section in proton-proton collisions. The model implements a mixture of two different formalisms. It uses the Double Parton Scattering (DPS) to describe the production of two quark pairs (a $q_1\bar{q}_1$ plus a $q_2\bar{q}_2$) and uses the Color Evaporation Model (CEM) to describe the coalescence of the two quark pairs in a compact tetraquark state. After using the experimental value of the X(3872) production cross section announced by the CMS collaboration we fixed the parameters of our model at 7 TeV and make predictions for 14 TeV. We also make predictions for the production cross section of the $T_{4c}$, a tetraquark composed of 2 $c\bar{c}$ pairs, for the energies of the LHC.
