资源简介:
CERN-LHC. Measurement of the jet shapes in top-quark pair events from proton-proton collisions at a centre-of-mass energy of 7 TeV. The analysis uses a data sample of integrated luminosity 1.8 fb-1. Jets are reconstructed using the anti-kT algorithm with jet radius R=0.4. Jet shapes are presented as differential and integrated defined as: Differential (RHO) - scalar sum of jet PT in an annulus of thickness deltaR around radius r / scalar sum of jet PT in the cone of radius R. Integrated (PSI) - scalar sum of jet PT in cone radius r / scalar sum of jet PT in cone radius R. Data are shown separated into b-jets and light-jet events. UPDATE (22 JUL 2014): Information on the different sources of systematic uncertainty is given in the following four links, containing tables with the relative values of the uncertainty (in %) for both the differential (Diff) and integrated (Int) versions of the jet shapes for both light- (lJets) and b-jets (bJets). The uncertainties indicated with (Up) and (Down) are asymmetric, while the rest are symmetric on each bin.

欧洲核子研究组织(CERN)大型强子对撞机(LHC):针对质心能量为7 TeV的质子-质子碰撞产生的顶夸克对事件,开展喷注形状(jet shapes)测量。本分析使用积分亮度为1.8 fb⁻¹的数据集样本。喷注通过反kT(anti-kT)算法重建,喷注半径R=0.4。喷注形状以微分形式与积分形式分别呈现,定义如下:微分形式(RHO):以半径r为中心、厚度为ΔR的环形区域内的喷注横向动量(transverse momentum, PT)标量和,除以半径为R的锥体内喷注横向动量标量和;积分形式(PSI):半径为r的锥体内喷注横向动量标量和,除以半径为R的锥体内喷注横向动量标量和。数据按b喷注(b-jets)与轻味喷注(light-jets)事件分别展示。 更新说明(2014年7月22日):不同系统不确定性来源的相关信息通过以下四个链接提供,其中包含轻味喷注(lJets)与b喷注(bJets)的喷注形状微分(Diff)与积分(Int)版本的相对不确定性(以百分比为单位)表格。标注有(Up)与(Down)的不确定性为非对称不确定性,其余各分箱的不确定性均为对称不确定性。
