"Table 40" of "Charged jet cross sections and properties in proton-proton collisions at $\sqrt{s}=7$ TeV"

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）实验中，针对质心系能量$sqrt{s}=7$ TeV的最小偏置质子-质子碰撞，测量了带电喷注微分截面（differential charged jet cross sections）、喷注碎裂分布（jet fragmentation distributions）及喷注形状（jet shapes）；其中喷注形状包括喷注带电粒子多重数、包含重建喷注横向动量$p_{
m T}$80%的平均半径，以及径向横向动量分布。本实验通过对中间快度区域的带电粒子动量，采用顺序重组$k_{
m T}$、反$k_{
m T}$以及SISCone喷注寻迹算法进行喷注重建，算法的分辨参数$R$取值范围为0.2至0.6。针对横向动量区间$20 < p_{
m T}^{
m jet,ch} < 100 mathrm{GeV}/c$内的喷注，采用三种喷注寻迹算法测量了其喷注微分产生截面；而针对$p_{
m T}$处于20至80 $mathrm{GeV}/c$区间的喷注，则给出了喷注碎裂分布与喷注形状的测量结果。本结果将与事件产生器（PYTHIA、HERWIG、PHOJET）的模拟结果进行对比，对比覆盖未扣除本底事件（UE）以及扣除本底事件两种情形。
