论文摘要
我们研究了将库仑相互作用添加到通过夸克 - 胶状等离子体传播的重part量谐波振荡器（HO）近似（HO）的效果（Molliere理论的QCD扩展）。我们明确地发现了在莫利理论的框架中，在夸克gluon等离子体中繁殖夸克辐射的横向动量分布的表达，同时考虑了谐波振荡器（HO）近似值中的BDMPSZ辐射，以及其他潜在的潜在潜力。我们表明，这些库仑对数显着影响BDMPSZ作品中的HO分布，尤其是对于小的横向动量，填充死锥，并减少对重夸克辐射的死锥抑制（死锥效应）。此外，我们研究了相空间限制对重夸克能量损失的影响，并认为考虑到相空间限制和库仑胶子的影响会降低重夸克能量损失对HO近似中MAS的依赖性。
We study the effects of adding the Coulomb interactions to the harmonic oscillator (HO) approximation of the heavy parton propagating through the quark-gluon plasma (the extension to QCD of the Molliere theory). We explicitly find the expression for the transverse momentum distribution of the gluon radiation of the heavy quark propagating in the quark gluon plasma in the framework of the Moliere theory, taking into account the BDMPSZ radiation in the harmonic oscillator (HO) approximation, and the Coulomb logarithms described by the additional logarithmic terms in the effective potential. We show that these Coulomb logarithms significantly influence the HO distribution, derived in the BDMPSZ works, especially for the small transverse momenta, filling the dead cone, and reducing the dead cone suppression of the heavy quark radiation (dead cone effect). In addition we study the effect of the phase space constraints on the heavy quark energy loss, and argue that taking into account of both the phase space constraints and of the Coulomb gluons reduces the dependence of the heavy quark energy loss on its mas in the HO approximation.
