资源简介:

CERN-LHC. The differential charged jet cross sections, jet fragmentation distributions, and jet shapes, such as jet charged particle multiplicity, average radius containing 80% of the reconstructed jet $p_{\rm T}$, and radial transverse momentum distributions, are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=$ 7 TeV. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R$ = 0.2 -- 0.6. Differential jet production cross sections are measured with the three jet finders in the transverse momentum interval 20 $< p_{\rm T}^{\rm jet,ch} <$ 100 GeV/$c$ while jet fragmentation and jet shapes are reported for jets in the $p_{\rm T}$ range 20 -- 80 GeV/$c$. Results are presented in comparison to event generators (PYTHIA, HERWIG, PHOJET), for both, without subtraction of underlying events (UE) and after UE subtraction.

欧洲核子研究中心大型强子对撞机(CERN-LHC)数据集:本数据集在质心系能量$sqrt{s}=7 mathrm{TeV}$的最小偏置质子-质子碰撞(minimum bias proton-proton collisions)中,测量了微分带电喷注截面、喷注碎裂分布以及喷注形状——其中喷注形状包含喷注带电粒子多重数、包含80%重建喷注横向动量$p_{ m T}$的平均半径,以及径向横向动量分布。喷注通过中等快度区域内的带电粒子动量重建,采用顺序重组$k_{ m T}$、反-$k_{ m T}$以及SISCone喷注寻迹算法,分辨参数$R$的取值范围为$0.2sim0.6$。针对三种喷注寻迹算法,微分喷注产生截面的测量横向动量区间为$20 < p_{ m T}^{{ m jet,ch}} < 100 mathrm{GeV}/c$;而喷注碎裂分布与喷注形状的测量对象为横向动量范围$20sim80 mathrm{GeV}/c$的喷注。本结果与事件产生器(PYTHIA、HERWIG、PHOJET)的模拟结果进行对比,分别覆盖未减除本底事件(UE)与已完成本底事件减除两种情形。
