7 TeV的$pp$碰撞中喷流诱导的脊的形成

Ridge Formation Induced by Jets in $pp$ Collisions at 7 TeV

Rudolph C. Hwa, C. B. Yang

摘要:

在7 TeV的PP碰撞中发现的脊现象的解释给出的软部分子的增强,由于半硬射流的能量损失。在核碰撞中脊形成的描述可以直接扩展到pp碰撞,因为不使用流体力学,方位各向异性产生的半硬散射。p_T和重数依赖性都很好地再现。对其他观测量提出了一些建议。

英文摘要:

An interpretation of the ridge phenomenon found in pp collisions at 7 TeV is given in terms of enhancement of soft partons due to energy loss of semihard jets. A description of ridge formation in nuclear collisions can directly be extended to pp collisions, since hydrodynamics is not used, and azimuthal anisotropy is generated by semihard scattering. Both the p_T and multiplicity dependencies are well reproduced. Some suggestions are made about other observables.
