Tevatron喷注中带电强子的横动量谱

Transverse momentum spectra of charged hadrons in jets at the Tevatron

Redamy Perez Ramos

摘要:

本文确定了高能喷流内部的强子$\kt$ -谱,包括相对于修正的前导对数近似(MLLA)、极限谱近似(假定红外截止$Q_0 =\lqcd$)和极限谱近似($Q_0\ne\lqcd$)的相对幅度修正$\cO{\sqrt{α_s}}$。在限制频谱近似的结果被发现,归一化后,在令人印象深刻的协议与测量的CDF合作。还报道了一个新的“驼背”高原的积分表示。

英文摘要:

The hadronic $\kt$-spectrum inside a high energy jet is determined including corrections of relative magnitude $\cO{\sqrt{α_s}}$ with respect to the Modified Leading Logarithmic Approximation (MLLA), in the limiting spectrum approximation (assuming an infrared cut-off $Q_0 =\lqcd$) and beyond ($Q_0\ne\lqcd$). The results in the limiting spectrum approximation are found to be, after normalization, in impressive agreement with measurements by the CDF collaboration. A new integral representation for the "hump-backed" plateau is also reported.
