J/ψ and charm at RHIC

A comprehensive overview of charm-related measurements by the PHENIX Collaboration at RHIC is presented.It is shown that Cold Nuclear Matter (CNM) effects cannot be understood in terms of just shadowing and constant breakup cross-section.There are indications of J/ψ suppression in most central Au + Au collisions beyond CNM effects.Open charm suppression and flow in Au + Au collisions is similar to that of light quarks.
