PHENIX results on direct photon production from Au+Au collisions
<!--HTML-->PHENIX measurements of low $p_T$ direct photons in Au+Au collisions at 200 GeV show large yields that have simultaneously a large anisotropies with respect to the reaction plane, and that scale with the charged multiplicity to a power of 5/4, independent of transverse momentum and...

description | <!--HTML-->PHENIX measurements of low $p_T$ direct photons in Au+Au collisions at 200
GeV show large yields that have simultaneously a large anisotropies with
respect to the reaction plane, and that scale with the charged multiplicity
to a power of 5/4, independent of transverse momentum and collision
centrality. Calculations of thermal photon emission fall short in describing
these three features. Furthermore, a recent publication of the STAR
collaboration indicates lower direct photon yields in Au+Au collisions than
observed by PHENIX. In order to provide new PHENIX has shown first results
from Au+Au data taken in 2014. These data have 10 fold statistics compared
to published results. In this talk we will show the latest direct photon
results from this data set. |
