“…That mechanism potentially moderates the large suppression observed in Au+Au collisions at √ s N N = 200 GeV. It is notable that in central Au+Au collisions at √ s N N = 62 GeV an enhancement is also observed at intermediate p T [22].…”

The PHENIX Collaboration at the Relativistic Heavy Ion Collider has measured open heavy flavor production in minimum bias Au+Au collisions at √ s N N = 200 GeV via the yields of electrons from semileptonic decays of charm and bottom hadrons. Previous heavy flavor electron measurements indicated substantial modification in the momentum distribution of the parent heavy quarks due to the quark-gluon plasma created in these collisions. For the first time, using the PHENIX silicon vertex detector to measure precision displaced tracking, the relative contributions from charm and bottom hadrons to these electrons as a function of transverse momentum are measured in Au+Au collisions. We compare the fraction of electrons from bottom hadrons to previously published results extracted from electron-hadron correlations in p+p collisions at √ s N N = 200 GeV and find the fractions to be similar within the large uncertainties on both measurements for pT > 4 GeV/c. We use the bottom electron fractions in Au+Au and p+p along with the previously measured heavy flavor electron RAA to calculate the RAA for electrons from charm and bottom hadron decays separately. We find that electrons from bottom hadron decays are less suppressed than those from charm for the region 3 < pT < 4 GeV/c.

“…It has been one of the major qualitative discoveries of the heavy ion collision program at RHIC and LHC that charm quarks appear to flow about as efficiently as light quarks do (see, e.g., refs. [8][9][10] and references therein). That a flow develops is an example of a relaxation towards local thermal equilibrium.…”

Nonperturbative estimate of the heavy quark momentum diffusion coefficient

et al. 2015

We estimate the momentum diffusion coefficient of a heavy quark within a pure SU(3) plasma at a temperature of about 1.5T c . Large-scale Monte Carlo simulations on a series of lattices extending up to 192 3 × 48 permit us to carry out a continuum extrapolation of the so-called colour-electric imaginary-time correlator. The extrapolated correlator is analyzed with the help of theoretically motivated models for the corresponding spectral function. Evidence for a non-zero transport coefficient is found and, incorporating systematic uncertainties reflecting model assumptions, we obtain κ = (1.8 − 3.4) T 3 . This implies that the "drag coefficient", characterizing the time scale at which heavy quarks adjust to hydrodynamic flow, is η −1 D = (1.8 − 3.4)(T c /T ) 2 (M/1.5GeV) fm/c, where M is the heavy quark kinetic mass. The results apply to bottom and, with somewhat larger systematic uncertainties, to charm quarks.

“…Since dark matter is such an exciting area of current research, the WASA limit could not be the last word on the subject. In the year that followed there were measurements by collaborations at HADES [342], BaBar [343], MAMI [344], PHENIX [345], and NA48/2 [346] and the much stricter upper limits found by summing all these later results seem to exclude almost completely dark photons as being the origin of the g-2 discrepancy. However, in general these were inclusive measurements and the WASA data still represents the best exclusive measurement of the Dalitz decay of the π 0 .…”
