高能-重离子碰撞中近侧喷注的脊

The Ridge Associated with the Near-side Jet in High Energy-Heavy-Ion Collisions

Cheuk-Yin Wong

摘要:

与近侧喷流相关联的脊粒子被识别为被近表面喷流踢出的中等部分子。它们携带着关于喷流-部分子碰撞时刻的部分子动量分布和纵向动量反冲的大小的直接信息。提取的早期部分子动量分布具有类热横向动量分布的快度平台结构。这样的快度平台结构可能来自于通量管中的粒子产生,因为色电荷和反色电荷在高能量下分离。

英文摘要:

The ridge particles associated with a near-side jet are identified as medium partons kicked by the jet near the surface. They carry direct information on the parton momentum distribution at the moment of jet-parton collisions and the magnitude of the longitudinal momentum kick. The extracted early parton momentum distribution has a rapidity plateau structure with a thermal-like transverse momentum distribution. Such a rapidity plateau structure may arise from particle production in flux tubes, as color charges and anti-color charges separate at high energies.
