| Publication Abstract: | We study the behaviour of the ?c1(3872), also known as X(3872), in dense nuclear matter. We begin from a picture in vacuum of the resonance as a pureply molecular (D¯D? ? c.c.) state, generated as a bound state from a heavy-quark symmetry leading-order interaction between the charmed mesons, and analyze the D¯D? scattering T?matrix (TD¯D ?) inside of the medium. Next, we consider also mixed-molecular scenarios and, in all cases, we determine the corresponding X(3872) spectral function and the D¯D ? amplitude, with the mesons embedded in the dense environment. We find important nuclear corrections for TD¯D? and the pole position of the resonance, and discuss the dependence of these results on the D¯D? molecular component in the X(3872) wave-function. These predictions could be tested in the finite-density regime that can be accessed in the future CBM and PANDA experiments at FAIR. |
