Dielectron continuum production from $\sqrt{s_{NN}}$ = 200 GeV p + p and Au + Au collisions at STAR
Dielectron continuum production sqrt Au + Au collisions STAR
2011/7/20
We present the first STAR dielectron measurement in 200 GeV p + p and Au + Au collisions. Results are compared to hadron decay cocktails to search for vector meson in-medium modification in low mass r...
I present recent results from jets and jet-like correlation measurements from STAR. The pp data are compared to those from Au-Au collisions to attempt to infer information on the medium produced and h...
We present the first results using the STAR detector from the Beam Energy Scan (BES) program at the Relativistic Heavy-Ion Collider (RHIC). In this program, Au ion collisions at center of mass energie...
STAR Measurements of Bottom to Charm Ratio and Heavy Quark Interaction with the QCD Medium through Non-Photonic Electron-Hadron Correlations
STAR Charm Ratio Heavy Quark Interaction QCD Medium
2011/7/20
We present STAR measurements of relative charm and bottom contributions to NPE from $p+p$ collisions at $\sqrt{s}$= 200 and 500 GeV energies. We report the total bottom quark production cross section ...
Gluon polarization measurements with inclusive jets at STAR
Gluon polarization inclusive jets STAR
2011/7/20
At RHIC kinematics, polarized jet hadroproduction is dominated by $gg$ and $qg$ scattering, making the jet double longitudinal spin asymmetry, $A_{LL}$, sensitive to gluon polarization in the nucleon....
