收藏资源简介:
CERN-LHC. Measurements of the ratio, Rcp, between jet production in the central to peripheral regions in Lead Lead collisions at a centre of mass energy/nucleon of 2.76 TeV. Jets are reconstructed with |eta|<2.1, covering the jet PT range 38-210 GeV, using the anti-Kt algorithm with norminal jet radii of R=0.2, 0.3, 0.4 and 0.5. Seven regions of centrality are considered from the most peripheral of 60-80% to the most central 0-10%. Rcp is studied as a function of jet PT, number of participating nucleons NPART and R for each of the centrality regions, as well as the ratio of Rcp/Rcp(R=0.2) as a function of jet PT for each R=0.3, 0.4 and 0.5. Finally values of the covariance matrix for staistical correlations between jet PT bins are given. In the tables the first systematic errors are from JES, JER, efficiency, xin and Rcoll and are 100% correlated in PT. The second systematic errors are those that are partially correlated or uncorrelated in pt, taken to be 100% uncorrelated, from the regularization parameter.
欧洲核子研究中心大型强子对撞机(CERN-LHC):针对每核子质心系能量为2.76 TeV的铅-铅碰撞,测量中心区域与外周区域的喷注产额比Rcp。喷注通过|η|<2.1的条件重建,覆盖喷注横动量(Transverse Momentum,简称PT)38~210 GeV的区间,采用标称喷注半径R=0.2、0.3、0.4和0.5的反k_t喷注算法(anti-Kt algorithm)。本次分析共考虑7个碰撞中心度区间,覆盖从最外周的60%~80%至最中心的0%~10%。针对每一碰撞中心度区间,分析Rcp随喷注横动量、参与核子数(number of participating nucleons,简称NPART)及喷注半径R的依赖关系;同时针对R=0.3、0.4、0.5三种喷注半径,分别分析Rcp与R=0.2时Rcp的比值随喷注横动量的依赖关系。最后还给出了喷注横动量区间间统计相关性的协方差矩阵数值。在各数据表中,第一类系统误差来自喷注能量标度(Jet Energy Scale,简称JES)、喷注能量分辨率(Jet Energy Resolution,简称JER)、探测效率、xin以及Rcoll,且在横动量区间内呈100%相关性。第二类系统误差来自正则化参数,在横动量区间内呈部分相关或不相关,本次分析中将其视为100%不相关。
