【 摘 要 】

We develop a formalism to study the tetraquark production in hadronic collisions. We focus on double parton scattering and formulate a version of the color evaporation model for the production of the T4ctetraquark, a state composed by the quarks. We find that the production cross section grows rapidly with the collision energy and the T4cmight be observable at LHC energies.
