Physics - Nuclear Physics Seminar

The nonperturbative nature of the strong force leads to a wide range of mechanisms in which the production hadrons in high energy particle collisions can be modified.  One such example, the relative suppression of excited states of heavy quark-antiquark pairs known as quarkonia, compared to their ground state, is considered a hallmark property of the hot quark-gluon plasma (QGP) that is created in relativistic heavy ion collisions.  A similar suppression pattern has been observed in small systems such as proton-ion collisions, potentially lending further credence to the hypothesis that a QGP "droplet" is formed in these collisions.  In this talk I will discuss the current status of quarkonia suppression measurements in small systems and describe a new analysis by the CMS experiment studying charmonium suppression as a function of the number of charged particles produced in the collision.  The data will be compared with an alternative "comover" model which does not invoke the need for QGP production.  In the last part of the talk, I will detail plans for a future detector at the upcoming electron-ion collider (EIC) which will allow physicists to further probe the nature of hadronizaton in cold nuclear matter with exquisite precision.
