AI总结:

针对DIS实验中底强子产生研究困难的问题,提出基于事件拓扑和displaced vertices的重味事件识别算法,模拟显示其在EIC上具备发现质子内intrinsic bottom quarks的潜力。

摘要:

由于产生率和分支比很小,在深度非弹性散射(DIS)实验中研究重味强子产生,特别是底强子产生,十分困难。为克服这些限制,提出了一种基于事件拓扑来识别重味DIS事件的方法。基于为LHCb实验开发的重味喷注标记策略,该算法使用 displaced vertices 来识别重味强子的衰变。通过模拟展示了该算法在 Electron-Ion Collider 上的性能,并表明它为质子中非微扰 intrinsic bottom quarks 提供了发现潜力。

英文摘要:

Heavy-flavor hadron production, in particular bottom hadron production, is difficult to study in deep-inelastic scattering (DIS) experiments due to small production rates and branching fractions. To overcome these limitations, a method for identifying heavy-flavor DIS events based on event topology is proposed. Based on a heavy-flavor jet tagging strategy developed for the LHCb experiment, this algorithm uses displaced vertices to identify decays of heavy-flavor hadrons. The algorithm's performance at the Electron-Ion Collider is demonstrated using simulation, and it is shown to provide discovery potential for non-perturbative intrinsic bottom quarks in the proton.
