LHC能源的基础事件研究

Underlying Event Studies for LHC Energies

Gergely Gábor Barnaföldi, András G. Agócs, Péter Lévai

摘要:

基础事件最初是由CDF协作在几十年前定义的。在这里,我们改进了原来的定义,以扩展我们的分析与多射流的事件。我们介绍了一个定义为周围的环/带,并根据此定义的射流和周围带排除区域将提供一个很好的基本事件的定义。我们通过定义的几何中的多重性来研究我们的定义。同时,在$\sqrt{s}=7$ TeV LHC能量的质子-质子碰撞中,也研究了这些区域的平均横动量。

英文摘要:

Underlying event was originally defined by the CDF collaboration decades ago. Here we improve the original definition to extend our analysis for events with multiple-jets. We introduce a definition for surrounding rings/belts and based on this definition the jet- and surrounding-belt-excluded areas will provide a good underlying event definition. We inverstigate our definition via the multiplicity in the defined geometry. In parallel, mean transverse momenta of these areas also studied in proton-proton collisions at $\sqrt{s}=7$ TeV LHC energy.
