Title: Beautiful melting: The suppression of Upsilon states in heavy ion collisions

Speaker: Professor Manuel Calderon de la Barca Sanchez (UC Davis)

Abstract:

In the study of the thermodynamics of QCD, the theory of the strong interaction, it is expected that at high temperature the color charges will be deconfined from hadrons in a state we call the Quark-Gluon Plasma. It was predicted that color deconfinent would lead to melting of heavy quarkonia via color Debye screening. In this talk, I will review the measurement of Upsilon states, mesons composed of heavy beauty and anti-beauty quarks, in heavy ion collisions with the CMS detector. The dramatic melting of the Upsilon states is one of the best pieces of evidence we have consistent with the formation of a QGP, and they can help elucidate just how hot it actually is via model-dependent estimates of the medium temperature.

Time: June 15th, 2022 at 11.00 AM.
