论文摘要
我们提出了使用AD/CFT技术抑制B-Meson的预测，假设$ \ sqrt {s_ {nn}} = 2.76 $ TEV的中央碰撞和$ \ sqrt {s_s_ {s_ {s_ {nn}} = 5.5 $ TEV的QUARK-GLUON等离子体的强烈耦合。我们提供了由于1）将QCD参数映射到$ \ \ \ \ Mathcal n = 4 $ sym和2）ADS/CFT预测扩散系数的动量依赖性的确切形式的QCD参数映射的估计值。我们表明，以$ \ sim 25 $ gev/c的订单，将能量损失与流量的耦合增加了$ v_2 $，从而大大增加了$ v_2 $，因此指出了$ r_ {aa} $和$ v_2 $ puzzzle for Light Hadrons的可能分辨率。
We present predictions for the suppression of B-mesons using AdS/CFT techniques assuming a strongly coupled quark-gluon plasma at $\sqrt{s_{NN}}=2.76$ TeV for central collisions and $\sqrt{s_{NN}}=5.5$ TeV for various centrality classes. We provide estimates of the systematic theoretical uncertainties due to 1) the mapping of QCD parameters to those in $\mathcal N = 4$ SYM and 2) the exact form of the momentum dependence of the diffusion coefficient predicted by AdS/CFT. We show that coupling energy loss to flow increases $v_2$ substantially out to surprisingly large momenta, on the order of $\sim 25$ GeV/c, thus pointing to a possible resolution of the $R_{AA}$ and $v_2$ puzzle for light hadrons.
