强子对撞机喷流中强子的方位不对称分布

Azimuthal Asymmetric Distribution of Hadrons Inside a Jet at Hadron Collider

Feng Yuan

摘要:

本文研究了单横极化质子-质子散射中高能喷注中强子的方位非对称分布,它是由Collins效应乘以夸克横度分布引起的.我们认为,在这个过程中的柯林斯函数是相同的,在半包含深非弹性散射。对这一过程的实验研究将为我们提供关于夸克横观分布的重要信息,并检验碎裂函数的普适性。

英文摘要:

We study the azimuthal asymmetric distribution of hadrons inside a high energy jet in the single transverse polarized proton proton scattering, coming from the Collins effect multiplied by the quark transversity distribution. We argue that the Collins function in this process is the same as that in the semi-inclusive deep inelastic scattering. The experimental study of this process will provide us important information on the quark transversity distribution and test the universality of the fragmentation functions.
