Abstract. Since its first detection, the interesting properties of the Tcc(3875)+ have made it to be one of the most prominent tetraquark-like states up to date. In this work we present a joint analysis of the T+cc and its charge-conjugated partner in a dense nuclear medium. We start by considering both states as purely isoscalar D* D and D¯*D¯ S -wave bound states, respectively. We use previous results for the in-medium D, D¯*D¯, D* and D* spectral functions to determine the modified two-meson amplitudes. We find important changes in the in-medium mass and width of both tetraquark-like resonances, which become more visible when increasing the nuclear density and molecular probabilities. The experimental confirmation of the found distinctive patterns will support the existence of molecular components in the T+cc and T-c¯c¯ wave functions.
