Charmonium propagation through a dense medium

Attenuation of a colourless c̄c dipole propagating with a large momentum through a hot medium originates from two sources, Debye screening (melting), and inelastic collisions with surrounding scattering centres (absorption). The former never terminates completely production of a bound charmonium in...
