电子-核深度非弹性散射中的重夸克产生

Heavy quark production in deep inelastic electron-nucleus scattering

V. P. Goncalves, M. S. Kugeratski, F. S. Navarra

摘要:

在过去的几年里,重夸克的产生在理论和实验上都得到了很好的研究。理论已被用于研究HERA的$e p$碰撞、Tevatron和RHIC的$pp$碰撞、RHIC的$pA$和$dA$碰撞以及CERN SPS和RHIC的$AA$碰撞中的重夸克产生。然而,据我们所知,在$eA$中的重夸克产生几乎没有受到关注。随着高能电子-离子对撞机的可能建造,需要更新重夸克产生的估计。我们从饱和物理的角度出发,用偶极模型计算了重夸克产生的截面。我们隔离阴影和非线性效应,显示它们的魅力结构功能和横向动量谱的影响。

英文摘要:

Heavy quark production has been very well studied over the last years both theoretically and experimentally. Theory has been used to study heavy quark production in $e p$ collisions at HERA, in $pp$ collisions at Tevatron and at RHIC, in $pA$ and $dA$ collisions at RHIC and in $AA$ collisions at CERN-SPS and at RHIC. However, to the best of our knowledge, heavy quark production in $eA$ has received almost no attention. With the possible construction of a high energy electron-ion collider, updated estimates of heavy quark production are needed. We address the subject from the perspective of saturation physics and compute the heavy quark production cross section with the dipole model. We isolate shadowing and non-linear effects, showing their impact on the charm structure function and on the transverse momentum spectrum.
