Description
We analyze the finite temperature potential of X(3872) in the Born-Oppenheimer approximation under the assumption that it is a tetraquark. At large number of colors, the potential is argued to consist in a real part plus a constant imaginary term. The former is calculated using as input at zero temperature lattice QCD determinations of the potential for hybrids. For its extension to finite temperatures, we adapt an approach by Rothkopf and Lafferty. In this framework, which can be applied to other suggested internal structures for the X(3872) and to other exotic states, we qualitatively estimate the temperature range for the formation of the heavy tetraquark and propose a picture for its in-medium dissociation. We then introduce a dynamic coalescence model to better understand how this particle forms and persist inside the thermal medium.
