Measurements of charged jet production as a function of centrality are presented for p-Pb collisions recorded at [Formula: see text] TeV with the ALICE detector. Centrality classes are determined via the energy deposit in neutron calorimeters at zero degree, close to the beam direction, to minimise dynamical biases of the selection. The corresponding number of participants or binary nucleon-nucleon collisions is determined based on the particle production in the Pb-going rapidity region. Jets have been reconstructed in the central rapidity region from charged particles with the anti-[Formula: see text] algorithm for resolution parameters [Formula: see text] and [Formula: see text] in the transverse momentum range 20 to 120 GeV/. The reconstructed jet momentum and yields have been corrected for detector effects and underlying-event background. In the five centrality bins considered, the charged jet production in p-Pb collisions is consistent with the production expected from binary scaling from pp collisions. The ratio of jet yields reconstructed with the two different resolution parameters is also independent of the centrality selection, demonstrating the absence of major modifications of the radial jet structure in the reported centrality classes.
给出了用ALICE探测器在[公式：见正文] TeV下记录的质子-铅离子碰撞中带电喷注产生量随中心度的变化情况。中心度类别通过零度附近靠近束流方向的中子量热计中的能量沉积来确定，以尽量减少选择的动力学偏差。相应的参与者数量或二元核子-核子碰撞数量基于铅离子向前快度区域中的粒子产生来确定。喷注是在中心快度区域从带电粒子中利用反[公式：见正文]算法重建的，分辨率参数为[公式：见正文]和[公式：见正文]，横向动量范围为20至120 GeV/。重建的喷注动量和产率已针对探测器效应和本底事件背景进行了校正。在所考虑的五个中心度区间内，质子-铅离子碰撞中的带电喷注产生与质子-质子碰撞二元标度预期的产生情况一致。用两种不同分辨率参数重建的喷注产率之比也与中心度选择无关，这表明在所报告的中心度类别中径向喷注结构没有重大改变。
