作为背景减除工具的喷射区域

Jet areas as a tool for background subtraction

Gregory Soyez

摘要:

在所有现代强子对撞机中,喷流都受到软背景的巨大影响:在大型强子对撞机中质子-质子碰撞的堆积,或者在RHIC或大型强子对撞机中重离子碰撞的潜在事件。在这些诉讼中,我们提出了一个通用的和简单的方法,射流面积的基础上,从射流减去软背景的贡献。这允许在密集环境中更精确地重建射流的运动学。

英文摘要:

In all modern hadronic colliders, jets recieve a large contribution from a soft background: pileup in the case of proton-proton collisions at the LHC, or the underlying event for heavy-ion collisions at RHIC or the LHC. In these proceedings, we present a generic and simple method, based on jet areas, to subtract the contribution of the soft background from the jets. This allows for more precise kinematic reconstruction of jets in dense environments.
