INT Program INT-14-3
Heavy Flavor and Electromagnetic Probes in Heavy Ion Collisions
September 15 - October 10, 2014
Dimuon invariant mass distribution in the CMS Pb+Pb radic √sNN = 2.76 TeV dataset, showing the fit results (blue curve). The dashed-red line shows the fit obtained by imposing the same value for Υ(1S) in pp and Pb+Pb collisions while the 2S/1S and 3S/1S ratios are fixed to the values obtained from the fit to the pp data. The plot is used to visually illustrate the level of suppression. Image credit: CERN
Heavy flavor and electromagnetic probes play an important role
in characterizing matter produced in relativistic heavy-ion collisions.
Thermal photons and dileptons were originally proposed to measure
the temperature of the system. Suppression of heavy quarkonia was proposed
by Matsui and Satz as a probe of deconfinement and as a thermometer of
the medium. Open heavy flavor production
provides important insight into the problem of thermalization and the
mechanism of energy loss.
In recent years RHIC has provided interesting results both on hidden
and open heavy flavor production, including Υ suppression
and J/ψ elliptic flow, as well as for dilepton production.
The start of LHC heavy-ion program
opened a new era in the physics of heavy flavor probes. For the
first time measurements of excited heavy bottomonium states appeared
and evidence for strong in-medium modification of open heavy flavor probes
was also found.
In the following we discuss separately the open problems and opportunities
in heavy quarkonium and open heavy flavor production and electromagnetic
probes in more detail emphasizing the common themes in these subtopics.
The proposed one month program aims to bring together the
different relevant theory
communities to achieve a quantitative understanding of these probes
in heavy-ion collisions, based on first principles.
We anticipate the active participation of experimentalists in all aspects of this program.
