LHC的射流能量流

Jet energy flow at the LHC

Yoshitaka Hatta, Takahiro Ueda

摘要:

本文通过数值求解Banfi,Marchesini和Smye(BMS)导出的演化方程,定量研究了喷注能量流,并将结果应用于LHC上的两个过程:从QCD背景中鉴别来自重电弱玻色子衰变的高pt喷注,以及BFKL引发的双喷注快度间隙的存活概率。作为一个副产品,我们发现一个隐藏的BMS方程的对称性,这是一个共形对称的残余。

英文摘要:

We present a quantitative study of energy flow away from jets by numerically solving the evolution equation derived by Banfi, Marchesini and Smye (BMS), and apply the result to two processes at the LHC: Discriminating high-p_t jets originating from decays of heavy electroweak bosons from the QCD background, and the survival probability of BFKL-initiated dijet rapidity gaps. As a byproduct, we find a hidden symmetry of the BMS equation which is a remnant of conformal symmetry.
