Moller理论中夸克-胶子等离子体中的重夸克能量损失

Heavy Quark Energy Loss in the Quark-Gluon Plasma in the Moller theory

B. Blok

摘要:

在Moller理论框架下研究了重夸克在夸克-胶子等离子体(QGP)中传播的能量损失,包括在谐振子(HO)近似下描述的作为BDMPSZ韧致辐射微扰的可能的大库仑模.我们推导出了描述整个发射胶子频率范围内能量损失的解析表达式。在小的频率范围内,对于大于死锥角的角度,能量损失由BDMPSZ机制控制,而对于较大的频率,它是由GLV不透明度展开中的N=1项描述。对于不同的重夸克路径值和不同的$m/E$比,我们估计了相应的猝灭率。

英文摘要:

We study the energy loss of a heavy quark propagating in the Quark-Gluon Plasma (QGP) in the framework of the Moller theory, including possible large Coulomb logarithms as a perturbation to BDMPSZ bremsstrahlung, described in the Harmonic Oscillator (HO) approximation. We derive the analytical expression that describes the energy loss in the entire emitted gluon frequency region. In the small frequencies region, for angles larger than the dead cone angle, the energy loss is controlled by the BDMPSZ mechanism, while for larger frequencies it is described by N=1 term in the GLV opacity expansion. We estimate corresponding quenching rates for different values of the heavy quark path and different $m/E$ ratios.
